It's possible to declare deferred shape array using the POINTER
statement, for example:
POINTER :: var(:)
When analyzing POINTER declarations, we were not capturing the array
specification information, if present. I fixed this by changing the
"Post" function for "parser::PointerDecl" to check to see if the
declaration contained a "DeferredShapeSpecList". In such cases, I
analyzed the shape and used to information to declare an "ObjectEntity"
that contains the shape information rather than an "UnknownEntity".
I also added a couple of small tests that fail to compile without these
changes.

Some operators have more than one name, e.g. operator(==), operator(.eq).
That was working correctly in generic definitions but they can also
appear in other contexts: USE statements and access statements, for
example.
This changes FindInScope to always look for each of the names for
a symbol. So an operator may be use-associated under one name but
declared private under another name and it will be the same symbol.
This replaces GenericSpecInfo::FindInScope which was only usable in
some cases.
Add a version of FindInScope() that looks in the current scope to
simplify many of the calls.

Change how generic operators and assignments are checked for
distinguishable procedures. Because of how they are invoked, available
type-bound generics and normal generics all have to be considered
together. This is different from how generic names are checked.
Move common part of checking into DistinguishabilityHelper so that it
can be used in both cases after the appropriate procedures have been
added.
Cache result of Procedure::Characterize(Symbol) in a map in
CheckHelper so that we don't have to worry about passing the
characterized Procedures around or the cost of recomputing them.
Add MakeOpName() to construct names for defined operators and assignment
for using in error messages. This eliminates the need for different
messages in those cases.
When the procedures for a defined operator or assignment are undistinguishable,
include the type name in the error message, otherwise it may be ambiguous.
Add missing check that procedures for defined operators are functions
and that their dummy arguments are INTENT(IN) or VALUE.

Implement cross-set EQUIVALENCE impossibility checking; fixes
an infinite loop on an erroneous test. Also fix substring
reference offset calculations in EQUIVALENCE discovered to
be incorrect during testing.

- Fixed IsConstantExpr to check C879
- Fixed bugs in few test cases - data01.f90, block-data01.f90,
pre-fir-tree02.f90
- Modified implementation of C8106 to identify all automatic objects
and modified equivalence01.f90 to reflect the changes

Summary:
Some Symbol-related functions used in Evaluate were moved to
Evaluate/tools.h. This includes changing some member functions that were
replaced by non-member functions `IsDummy`, `GetUsedModule`, and
`CountLenParameters`.
Some member functions were made inline in `Scope`, `Symbol`,
`ArraySpec`, and `DeclTypeSpec`. The definitions were preceded by a
comment explaining why they are inline.
`IsConstantShape` was expanded inline in `IsDescriptor` because it isn't
used anywhere else
After this change, at least when compiling with clang on macos,
`libFortranEvaluate.a` has no undefined symbols that are satisfied by
`libFortranSemantics.a`.

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.
