In the USE statements that f18 emits to module files, ensure that symbols
from intrinsic modules are marked as such on their USE statements. And
ensure that the current working directory (".") cannot override the intrinsic
module search path when trying to locate an intrinsic module.

If a line is over 72 characters long, flang's preprocessor cuts it there
and continues on the next line.
For this purpose it uses the standard way of continuing line with & on each line.
However, it doesn't work with long compiler directives, like OpenMP or OpenACC ones.
The line that continues the directive also has to
contain the corresponding sentinel at the beginning.
This change implements the described functionality.
Also, some code was refactored in order to simplify and reuse existing code.

For "USE, INTRINSIC", search only for intrinsic modules;
for "USE, NON_INTRINSIC", do not recognize intrinsic modules.
Allow modules of both kinds with the same name to be used in
the same source file (but not in the same scoping unit, a
constraint of the standard that is now enforced).
The symbol table's scope tree now has a single instance of
a scope with a new kind, IntrinsicModules, whose children are
the USE'd intrinsic modules (explicit or not). This separate
"top-level" scope is a child of the single global scope and
it allows both intrinsic and non-intrinsic modules of the same
name to exist in the symbol table. Intrinsic modules' scopes'
symbols now have the INTRINSIC attribute set.
The search path directories need to make a distinction between
regular directories and the one(s) that point(s) to intrinsic
modules. I allow for multiple intrinsic module directories in
the second search path, although only one is needed today.

Rename the current -E option to "-E -Xflang -fno-reformat".
Add a new Parsing::EmitPreprocessedSource() routine to convert the
cooked character stream output of the prescanner back to something
more closely resembling output from a traditional preprocessor;
call this new routine when -E appears.
The new -E output is suitable for use as fixed form Fortran source to
compilation by (one hopes) any Fortran compiler. If the original
top-level source file had been free form source, the output will be
suitable for use as free form source as well; otherwise there may be
diagnostics about missing spaces if they were indeed absent in the
original fixed form source.
Unless the -P option appears, #line directives are interspersed
with the output (but be advised, f18 will ignore these if presented
with them in a later compilation).
An effort has been made to preserve original alphabetic character case
and source indentation.
Add -P and -fno-reformat to the new drivers.
Tweak test options to avoid confusion with prior -E output; use
-fno-reformat where needed, but prefer to keep -E, sometimes
in concert with -P, on most, updating expected results accordingly.

In parser::AllCookedSources, implement a map from CharBlocks to
the CookedSource instances that they cover. This permits a fast
Find() operation based on std::map::equal_range to map a CharBlock
to its enclosing CookedSource instance.
Add a creation order number to each CookedSource. This allows
AllCookedSources to provide a Precedes(x,y) predicate that is a
true source stream ordering between two CharBlocks -- x is less
than y if it is in an earlier CookedSource, or in the same
CookedSource at an earlier position.
Add a reference to the singleton SemanticsContext to each Scope.
All of this allows operator< to be implemented on Symbols by
means of a true source ordering. From a Symbol, we get to
its Scope, then to the SemanticsContext, and then use its
AllCookedSources reference to call Precedes().

Avoid spurious and confusing macro replacements from things like
-DPIC on Fortran source files whose suffixes indicate that preprocessing
is not expected.
Add gfortran-like "-cpp" and "-nocpp" flags to f18 to force predefinition
of macros independent of the source file suffix.

Hew more closely to the C17 standard; perform macro replacement

These are owned by an instance of a new class AllCookedSources.
This removes the need for a Scope to own a string containing
a module's cooked source stream, and will enable errors to be
emitted when parsing module files in the future.

Objects that are storage associated by EQUIVALENCE and
initialized with DATA are initialized by creating a
compiler temporary data object in the same scope,
assigning it an offset, type, and size that covers the
transitive closure of the associated initialized original
symbols, and combining their initializers into one common
initializer for the temporary.
Some problems with offset assignment of EQUIVALENCE'd objects
in COMMON were exposed and corrected, and some more error
cases are checked.
Remove obsolete function.
Small bugfix (nested implied dos).
Add a test.
Fix struct/class warning.

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.
