-fms-compatibility-version was defaulting to 18 (VS 2013), which is a pain if your environment is pointing to version 19 (VS 2015) libraries.
If cl.exe can be found, this patch uses its version number as the default instead. It re-uses the existing code to find the Visual Studio binaries folder and WinAPI methods to check its version. You can still explicitly specify a compatibility version on the command line. If you don't have cl.exe, this should be a no-op and you'll get the old default of 18.
This affected the tests, which assumed that if you didn't specific a version, that it would default to 18, but this won't be true for all machines. So a couple test cases had to be eliminated and a couple others had to be tweaked to allow for various outputs.

While using it in the shell is fine, this a problem when cc1as is

Fixes https://llvm.org/bugs/show_bug.cgi?id=27129 which is crash involving type
aliases and template type diffing. Template arguments for type aliases and
template arguments for the underlying desugared type may not have one-to-one
relations, which could mess us the attempt to get more information from the
desugared type. For type aliases, ignore the iterator over the desugared type.

Remove tests that have neither a triple nor an explicit -fmsc-version flag,
since in the absence of an -fmsc-version flag, the implicit value of the flag
is 17 (MSVC2013) with MSVC triples but 0 (not set) for other triples, and
the default triple is platform dependent.
This relands r263974 with a test fix.

Re-commit of r258950 after fixing layering violation.
The related LLVM patch adds a backend diagnostic type for reporting
unsupported features, this adds a printer for them to clang.
In the case where debug location information is not available, I've
changed the printer to report the location as the first line of the
function, rather than the closing brace, as the latter does not give the
user any information. This also affects optimisation remarks.

Summary:
MSVC's driver accepts all unknown arguments but warns about them. clang
by default rejects all unknown arguments. This causes issues
specifically with build systems such as autoconf which liberally pass
things such as $LDFLAGS to the compiler and expect everything to work.
This patch teaches clang-cl to ignore unknown driver arguments.

Remove an old assertion that does not hold. It is possible for a template
argument to be a declaration in one instantiation and an integer in another.
Create two new diff kinds for these (decl vs int and int vs decl).
llvm-svn: 257869
Save the integer type when diffing integers in template type diffing. When
integers are different sizes, print out the type along with the integer value.
Also with the type information, print true and false instead of 1 and 0 for
boolean values.
llvm-svn: 257861
If available, use the canonical template argument to fill in information for
template type diffing instead of attempting to special case and evaluate Expr's
for the value. Since those are the values used in template instantiation,
we don't have to worry about difference between our evaluator and theirs. Also
move the nullptr template arguments from DiffKind::Expression to
DiffKind::Declaration and allow DiffKind::Declaration to set an Expr. The only
effect that should result is that a named nullptr will show up as
'ptr aka nullptr' in diagnostics.
llvm-svn: 257853
1) Instead of using pairs of From/To* fields, combine fields into a struct
TemplateArgInfo and have two in each DiffNode.
2) Use default initialization in DiffNode so that the constructor shows the
only field that is initialized differently on construction.
3) Use Set and Get functions per each DiffKind to make sure all fields for the
diff is set. In one case, the Expr fields were not set.
4) Don't print boolean literals for boolean template arguments. This prevents
printing 'false aka 0'

When attempting to map a source into a given level of macro expansion,
this code was ignoring the possibility that the start and end of the
range might take wildly different paths through the tree of macro
expansions. It was assuming that the begin spelling location would
always precede the end spelling location, which is false. A macro can
easily transpose its arguments.
This also fixes a related issue where there are extra macro arguments
between the begin location and the end location. In this situation, we
now highlight the entire macro invocation.

With this change, most 'g' options are rejected by CompilerInvocation.
They remain only as Driver options. The new way to request debug info
from cc1 is with "-debug-info-kind={line-tables-only|limited|standalone}"
and "-dwarf-version={2|3|4}". In the absence of a command-line option
to specify Dwarf version, the Toolchain decides it, rather than placing
Toolchain-specific logic in CompilerInvocation.

specification) to an error. No compiler other than Clang seems to allow this,
and it doesn't seem like a useful thing to accept as an extension in general.
The current behavior was added for PR5957, where the problem was specifically
related to mismatches of the exception specification on the implicitly-declared
global operator new and delete. To retain that workaround, we downgrade the
error to an ExtWarn when the declaration is of a replaceable global allocation
function.
Now that this is an error, stop trying (and failing) to recover from a missing
computed noexcept specification. That recovery didn't work, and led to crashes
in code like the added testcase.

If we build with -Werror=implicit-function-declaration, only implicit
function declarations of non-library functions throw compiler errors.
For library functions, we only produce a warning. There is no way to
promote both of these cases to an error without promoting other
warnings.
It makes little sense to introduce an additional compiler flag just to
control this specific warning. In my opinion it should just be part of
the same group.

When displaying the macro backtrace, ignore some of the backtraces that do not
provide extra information to the diagnostic. Typically, if the problem is
entirely contained within a macro argument, the macro expansion is often not
needed. Also take into account SourceRange's attached to the diagnostic when
selecting which backtraces to ignore. Two previous test cases have also been
updated.
