Nico Weber cee4d85faf Split -Wmicrosoft into many specific warnings.
Also move "pragma comment" warning from -Wmicrosoft to -Wignored-pragmas.

-Wmicrosoft currently covers many different areas, some more useful than
others.  Split it into many targeted flags, so that projects can choose to
enable only a subset of these warnings.  This is also useful for incrementally
fixing and turning on these warnings.

-Wno-microsoft still disables all these warnings, and -Wmicrosoft still enables
them all.  After this change, it's possible to pass `-Wno-microsoft
-Wmicrosoft-unqualified-friend` to only enable -Wmicrosoft-unqualified-friend,
and `-Wmicrosoft -Wno-microsoft-unqualified-friend` to enable all other
Microsoft warnings.

I put all the template-related warnings behind -Wmicrosoft-template; if that
turns out to be too coarse we can make that finer later on. (In practice, I
haven't seen the template-related warnings fire frequently.)

Justin Bogner 203f09223b InstrProf: Fix a misuse of the FunctionDecl API when generating coverage
This was calling FD->hasBody(), meaning "Does the function that this
decl refers to have a body?", rather than
FD->doesThisDeclarationHaveABody(), meaning "Is this decl a
non-deleted definition?".

We might want to consider renaming these APIs :/

Renato Golin 7c542b4569 [ARM] Implement -Wa,-mfpu and friends for assemblers
This patch allows Clang to pass on -Wa,-mfpu, -Wa,-mhwdiv and
-Wa,-mcpu to the integrated assembler (via target-features), but
-march is still not being passed, but validated.

In case the command line has both -mxxx and -Wa,-mxxx, we warn
that the naked one will not be used in assembler mode.

Renato Golin e17c580034 [ARM] Changes to Arch/CPU handling to help with -Wa,-mfpu etc. (nfc)
To be able to handle -Wa, options in the assembler (ClangAs), we need to
make the handling of options based on the value of the options, not direct
Arguments from the list, since the list is immutable.

No functional change in this patch, but this allows validating of -Wa,-mfpu
and friends in the same way we validate -mfpu and friends, *just* for the
assembler.

Tyler Nowicki 54c020d372 Use CGLoopInfo to emit metadata for loop hint pragmas.
When ‘#pragma clang loop vectorize(assume_safety)’ was specified on a loop other loop hints were lost. The problem is that CGLoopInfo attaches metadata differently than EmitCondBrHints in CGStmt. For do-loops CGLoopInfo attaches metadata to the br in the body block and for while and for loops, the inc block. EmitCondBrHints on the other hand always attaches data to the br in the cond block. When specifying assume_safety CGLoopInfo emits an empty llvm.loop metadata shadowing the metadata in the cond block. Loop transformations like rotate and unswitch would then eliminate the cond block and its non-empty metadata.

This patch unifies both approaches for adding metadata and modifies the existing safety tests to include non-assume_safety loop hints.

Simon Pilgrim f81966d04b [X86] Add missing _m_prefetch intrinsic
The 3DNOW/PRFCHW cpu targets define both the PREFETCHW (set cache line modified) and PREFETCH (set cache line exclusive) instructions but only the _m_prefetchw (PREFETCHW) intrinsic is included in the header. This patch adds the missing _m_prefetch intrinsic.

I'm basing this off AMD documentation - the intel docs on the support for PREFETCHW isn't clear whether Silvermont/Broadwell properly support PREFETCH but given that the intrinsic implementation is a default __builtin_prefetch call, it is safe whatever.

David Majnemer 015ce0f68f [clang-cl] Handle -O correctly
We had multiple bugs here:
- We didn't support multiple optimization options in one argument.
  e.g. -O2y-
- We didn't correctly expand -O[12dx] to their respective options.
- We treated -O1 as clang -O1 instead of clang -Os.
- We treated -Ox as clang -O3 instead of clang -O2.  In fact, cl's -Ox
  option is *less* powerful than cl's -O2 option despite -Ox described
  as "Full Optimization".

This fixes PR24003.

 * Handle the __va_list_tag as a predefined decl. Previously we failed to merge
   sometimes it because it's not visible to name lookup. (In passing, remove
   redundant __va_list_tag typedefs that we were creating for some ABIs. These
   didn't affect the mangling or representation of the type.)

 * For Decls derived from Redeclarable that are not in fact redeclarable
   (implicit params, function params, ObjC type parameters), remove them from
   the list of expected redeclarable decls.

David Majnemer 5055dfcf4a [MS Extensions] Remove support for the i128 integer literal suffix
There is currently no support in MSVC for using i128 as an integer
literal suffix.  In fact, there appears to be no evidence that they have
ever supported this feature in any of their compilers.  This was an over
generalization of their actual feature and is a nasty source of bugs.
Why is it a source of bugs?  Because most code in clang expects that
evaluation of an integer constant expression won't give them something
that 'long long' can't represent.  Instead of providing a meaningful
feature, i128 gives us cute ways of exploding the compiler.
