Wire it through everywhere we have support for fastcall, essentially.
This allows us to parse the MSVC "14" CTP headers, but we will
miscompile them because LLVM doesn't support __vectorcall yet.

Original message:
Add a second late template parser callback meant to cleanup any
resources allocated by late template parsing. Call it from the
Sema::ActOnEndOfTranslationUnit method after all pending template
instantiations have been completed. Teach Parser::ParseTopLevelDecl to
install the cleanup callback when incremental processing is enabled so
that Parser::TemplateIds can be freed.

Clang supports __restrict__ as a function qualifier, but
DeclaratorChunk::FunctionTypeInfo lacked a field to track the qualifier's
source location (as we do with volatile, etc.). This was the subject of a FIXME
in GetFullTypeForDeclarator (in SemaType.cpp). This should also prove useful as
we add more warnings regarding questionable uses of the restrict qualifier.
There is no significant functional change (except for an improved source range
associated with the err_invalid_qualified_function_type diagnostic fixit
generated by GetFullTypeForDeclarator).

They cannot be written to, so marking them const makes sense and may improve
optimisation.
As a side-effect, SectionInfos has to be moved from Sema to ASTContext.
It also fixes this problem, that occurs when compiling ATL:
warning LNK4254: section 'ATL' (C0000040) merged into '.rdata' (40000040) with different attributes
The ATL headers are putting variables in a special section that's marked
read-only. However, Clang currently can't model that read-onlyness in the IR.
But, by making the variables const, the section does become read-only, and
the linker warning is avoided.

Specifically, avoid typo-correcting the variable name into a type before
typo-correcting the actual type name in the declaration. Doing so
results in a very unpleasant cascade of errors, with the typo correction
of the actual type name being buried in the middle.

Previously loop hints such as #pragma loop vectorize_width(#) required a constant. This patch allows a constant expression to be used as well. Such as a non-type template parameter or an expression (2 * c + 1).

__super appeared. Name lookup is performed in all base classes of the

r218292 reverted r197496 because it broke things. In addition to breaking
things, r197496 also made all traits starting with __is_ revertible.
Reinstantiate that part of r197496 because code out there (e.g. libc++) depends
on this behavior. Fixes PR21045.

Summary:
This fixes PR20023. In order to implement this scoping rule, we piggy
back on the existing LabelDecl machinery, by creating LabelDecl's that
will carry the "internal" name of the inline assembly label, which we
will rewrite the asm label to.

obviously supposed to be a parameter pack. Otherwise, warn if it immediately
follows a function parameter pack, because the user most likely didn't intend
to write a parameter pack followed by a C-style varargs ellipsis.
This warning can be syntactically disabled by using ", ..." instead of "...".

Array declarators involving the static keyword take on two forms:
D[ static type-qualifier-listopt assignment-expression ]
D[ type-qualifier-list static assignment-expression ]
