Summary:
Move InstantiateComponent and InstantiateIntrinsicType from symbol.cpp
to type.cpp as that is where they are called.
Put both in InstantiateHelper class to better isolate them.
Add CreateDerivedTypeSpec in InstantiateHelper.
Add non-const forms for AsIntrinsic and AsDerived to avoid const_cast.
No functional changes.

Currently, many `Flang :: Semantics` tests FAIL on Solaris. The failure
mode is always the same:
actual at 67: Name in ALLOCATE statement must be a variable name
expect at 67: ERROR: Name in ALLOCATE statement must be a variable name
It turns out the issue is twofold here:
- The awk script embedded in `flang/test/Semantics/common.sh` uses a string
value for `FS`, which isn't supported by traditional awk as documented in
the GNU autoconf manual.
- Even though /usr/gnu/bin (with gawk installed as awk) is in my build
environment's `PATH`, still /bin/awk is used
Although the proper fix would probably be to avoid the unportability, it's
easy to work around it for now. `common.sh` above is the only script in
the whole tree that for unknown reasons overrides `PATH` to
`/usr/bin:/bin`, unnecessarily creating this mess in the first place. Just
removing that setting easily avoids the issue.
Tested on `amd64-pc-solaris2.11` and `sparcv9-sun-solaris2.11`.

This class implements a switch-like dispatch statement for a value of 'T' using dyn_cast functionality. Each `Case<T>` takes a callable to be invoked if the root value isa<T>, the callable is invoked with the result of dyn_cast<T>() as a parameter.

Without this, the LLVM utilities (FileCheck) aren't built when running
`ninja check-flang` and it fails with:
llvm-project/llvm/utils/lit/lit/llvm/subst.py:134: fatal: Did not find FileCheck in...
Also the modules aren't built without depending on `module_files`, which

When building flang with LLVM HEAD, the unittests fail to link with ld.bfd or
ld.gold due to a linker ordering issue. Adding libSemantics as a dependency to
libEvaluate seems to fix that issue.

There is no printf formatting string for std::int64_t. Instead we have
to cast to std::intmax_t and use `%jd`. This change simplifies that by
automatically converting std::int64_t to std::intmax_t when formatting

In most cases, I just added the contraint names to the code and tests.
I implemented the following checks:
- C736 A child type with a coarray ultimate component must have a parent with
a coarray ultimate component.
- C737 A child type with and EVENT_TYPE or LOCK_TYPE component must have a
parent either which is EVENT_TYPE or LOCK_TYPE or a type with an EVENT_TYPE
or LOCK_TYPE component.
- C740 Sequence types must contain at least on component
- C740 Data components of sequence types must either be of an intrinsic type
or a sequenced derived type.
After implementing these checks, some tests had new errors unrelated to their
original purpose, so I fixed them.

In general all the basic functionality seems to work and removes some redundancy
and more complicated features in favor of borrowing infrastructure from LLVM
build configurations. Here's a quick summary of details and remaining issues:
* Testing has spanned Ubuntu 18.04 & 19.10, CentOS 7, RHEL 8, and
MacOS/darwin. Architectures include x86_64 and Arm. Without
access to Window nothing has been tested there yet.
* As we change file and directory naming schemes (i.e.,
capitalization) some odd things can occur on MacOS systems with
case preserving but not case senstive file system configurations.
Can be painful and certainly something to watch out for as any
any such changes continue.
* Testing infrastructure still needs to be tuned up and worked on.
Note that there do appear to be cases of some tests hanging (on
MacOS in particular). They appear unrelated to the build
process.
* Shared library configurations need testing (and probably fixing).
* Tested both standalone and 'in-mono repo' builds. Changes for
supporting the mono repo builds will require LLVM-level changes that
are straightforward when the time comes.
* The configuration contains a work-around for LLVM's C++ standard mode
passing down into Flang/F18 builds (i.e., LLVM CMake configuration would
force a -std=c++11 flag to show up in command line arguments. The
current configuration removes that automatically and is more strict in
following new CMake guidelines for enforcing C++17 mode across all the
CMake files.
* Cleaned up a lot of repetition in the command line arguments. It
is likely that more work is still needed to both allow for
customization and working around CMake defailts (or those
inherited from LLVM's configuration files). On some platforms agressive
optimization flags (e.g. -O3) can actually break builds due to the inlining
of templates in .cpp source files that then no longer are available for use
cases outside those source files (shows up as link errors). Sticking at -O2
appears to fix this. Currently this CMake configuration forces this in
release mode but at the cost of stomping on any CMake, or user customized,
settings for the release flags.
* Made the lit tests non-source directory dependent where appropriate. This is
done by configuring certain test shell files to refer to the correct paths
whether an in or out of tree build is being performed. These configured
files are output in the build directory. A %B substitution is introduced in
lit to refer to the build directory, mirroring the %S substitution for the
source directory, so that the tests can refer to the configured shell scripts.

The full list of constraints is C727, C728, C729, C730, C743, C755, C759, C778,
and C1543.
I added a function to tools.cpp to check to see if a symbol name is the name
of an intrinsic type.
The biggest change was to resolve-names.cpp to check to see if attributes were
either duplicated or in conflict with each other. I changed all locations
where attributes were set to check for duplicates or conflicts.
I also added tests for all checks and annotated the tests and code with the
numbers of the constraints being tested/checked.

The previous code had handling for cases when too many file descriptors may be
opened; this is not necessary with MemoryBuffer as the file descriptors are
closed after the mapping occurs. MemoryBuffer also internally handles the case
where a file is small and therefore an mmap is bad for performance; such files
are simply copied to memory after being opened.
Many places elsewhere in the code assume that the buffer is not empty, and the
old file opening code handles this by replacing an empty file with a buffer
containing a single newline. That behavior is now kept in the new MemoryBuffer
based code.

This patch replaces the occurrence of std::ostream by llvm::raw_ostream.
In LLVM Coding Standards[1] "All new code should use raw_ostream
instead of ostream".[1]
As a consequence, this patch also replaces the use of:
std::stringstream by llvm::raw_string_ostream or llvm::raw_ostream*
std::ofstream by llvm::raw_fd_ostream
std::endl by '\n' and flush()[2]
std::cout by llvm::outs() and
std::cerr by llvm::errs()
It also replaces std::strerro by llvm::sys::StrError** , but NOT in Fortran
runtime libraries
*std::stringstream were replaced by llvm::raw_ostream in all methods that
used std::stringstream as a parameter. Moreover, it removes the pointers to
these streams.

- C1550: binding label
- C1551: NON_RECURSIVE prefix
SubprogramMatchHelper performs all of these checks.

A separate-module-subprogram is declared as `module procedure ...`
and gets its characteristics from the declaration of that name as
a separate module procedure. When we encounter one, we need to create
symbols in the new subprogram scope for the dummy arguments and
function return (if any).
The failure to create these symbols led to the bug in issue flang-compiler/f18#1054:
when a dummy argument was referenced, the compiler interpreted it as
an implicit declaration because there was no symbol for the argument.

We have re-classified a subset of the regression tests as unit tests and
now we are porting the remaining ones.
Test discovery and running is now performed by lit rather than ctest.
The tests continue to use their original scripts with minor
modifications. Most of the changes were mechanical and so scripted.
A few changes were made by hand. Details
Manual:
* modfile09-*.f90 tests depend on being run together as some tests have
dependencies on modules created by other tests. This will need
separating out when porting away from test_modfile.sh, but for now,
added modfile09-*.f90 to the Inputs directory and added a single
tests modfile09.f90 to hold the run line.
* getdefinition03-a.f90 includes a non-test file getdefinition03-b.f90.
Manually edited the former to find the latter in Inputs so as to add
only one test.
* Same pattern for getsymbols03-{a,b}.f90
Auto:
* Remaining tests have a lit RUN line added to them based on the type
of test they are.
* Failing tests also have an XFAIL line added to them.
* Generic tests have their pre-existing RUN lines replaced with the
word "EXEC" to avoid conflict with the added lit RUN line.

for the compiler internals as opposed to being Fortran inputs to test
the compiler in action. The former style of tests are analog to LLVM's

These tests were disabled due to https://github.com/flang-compiler/f18/issues/407.
Previously these tests caused F18 to crash as the feature was not fully
implemented.
The altreturn feature is now implemented, so these tests can be
re-enabled. altreturn03 tested some negative cases which F18 correctly
diagnoses. Modified that test to expect these new error messages. Also
make the later cases in the test reachable.
These tests can now be ported by the script to lit-style tests.
