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.

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.

The check for whether a private component is accessible was depending on
determining whether the source range of the current scope was within the
source range of the module that the component was declared in. This
could fail if the current scope was of kind `ImpliedDos` and had no
source range.
The fix is to add `Scope::Contains` to check the relationship by
traversing the parent links. These are created when the Scope is so are
always reliable. The source range of a scope is built up over time.

One overload of WhyNotModifiable returned an optional message while the
other returns a unique_ptr. Change the latter to be consistent with the
former and other message-returning functions in this file.
Also, reorder the if clauses to reduce the level of indentation.

When a misparsed FunctionReference was converted to a StructureConstructor,
the components accessed were not checked for accessibility.
The conversion happens in expression analysis so that where the accessibity
must be checked. So move `CheckAccessibleComponent` to `tools.h` so that it
can be shared by `resolve-names.cpp` and `expression.cpp`.
Add FindModuleContaining to help implement this and use it other places.
Check that an access-spec can only appear in a module.
Remove some unnecessary "semantics::" qualifiers.

I've updated the compiler and test source with references to the contraints at
the points where they were enforced and tested. Many of these were already
implemented and required no code change. A few constraint checks were both
implemented and tested, and I only added references to the constraint
numbers in the compiler source and tests. Here are the things I had to
implement:
Constraint C716 states that, in a REAL constant, if both a kind-param and an
exponent letter appear, the exponent letter must be 'E'.
Constraints C715 and C719 require that a KIND value be actually implemented.
Constraint C722 requires that functions that return assumed-length character
types are external.
Constraint C726 disallows assumed lenght charater types for dummy arguments and
return types.
