Summary:
The keyword "template" isn't necessary when
printing a fully-qualified qualtype name, and, in fact,
results in a syntax error if one tries to use it. So stop
printing it.

Previously we would leave behind the old name specifier prefix, which
creates an invalid AST.  Other callers of CorrectTypo update their
CXXScopeSpec objects with the correction specifier if one is present.

Like cl.exe, clang-cl allows adding system include directories via the
INCLUDE env var.  Having a driver flag for this functionality is useful,
so add this too.

(In the future, we probably also want to have a flag alternative to
VCINSTALLDIR as used in MSVCToolChain::getVisualStudioBinaries(), and
a way to override the registry accesses in MSVCToolChain::getWindowsSDKDir()
-- maybe -ivcroot= and -iwinsdkroot=?).

I'd accidentally skipped the CMake check in a premature optimisation. I'd also
put the original test in completely the wrong place.

This patch fixes the following bugs in __builtin_classify_type implementation:
1) Support for member functions and fields
2) Same behavior as GCC in C mode (specifically, return integer_type_class for
   enums and pointer_type_class for function pointers and arrays). Behavior in
   C++ mode didn't changed.

Also, it refactors the whole implementation, by replacing a sequence of
if-else-if with a couple of switches.

In the case that the array indexing itself is within a type dependent context,
bail out of the evaluation.  We would previously try to symbolically evaluate
the expression which would then try to evaluate a non-address expression as an
address, triggering an assertion in Asserts builds.

We only need to consider the array subscript expression itself as in the case
that the base itself being type dependent is handled appropriately in EvalAddr.

Resolves PR26599.

Enable it for USRs and names when indexing.
Forward references can have different template argument names; including them
makes USRs and names unstable, since the name depends on whether we saw a forward reference or not.

C++ programs compiled for profiling (using `-pg`) should be linked with
`-lc++_p` (or `-lstdc++_p`, depending on the `-stdlib=` setting), not
with the regular C++ libraries.

Add a `FreeBSD::AddCXXStdlibLibArgs()` override to handle this, and add
a test case for it.  While here, extend the test case for the proper
passing of -lm and -lm_p.

Summary:
Unlike other outlined regions in OpenMP, offloading entry points have to have be visible (external linkage) for the device side. Using dots in the names of the entries can be therefore problematic for some toolchains, e.g. NVPTX.

Also the patch drops the column information in the unique name of the entry points. The parsing of directives ignore unknown tokens, preventing several target  regions to be implemented in the same line. Therefore, the line information is sufficient for the name to be unique. Also, the preprocessor printer does not preserve the column information, causing offloading-entry detection issues if the host uses an integrated preprocessor and the target doesn't (or vice versa).
