Saleem Abdulrasool b51bcaf2f0 Sema: prevent __declspec(naked) use on x64
MSDN (https://msdn.microsoft.com/en-us/library/h5w10wxs.aspx) indicates
that `__declspec(naked)` is only permitted on x86 and ARM targets.
Testing with cl does confirm this behaviour.  Provide a warning for use
of `__declspec(naked)` on x64.

Aaron Ballman 674cf26892 __declspec is not a core Clang language extension. Instead, require -fms-extensions or -fborland to enable the language extension.
Note: __declspec is also temporarily enabled when compiling for a CUDA target because there are implementation details relying on __declspec(property) support currently. When those details change, __declspec should be disabled for CUDA targets.

Ehsan Akhgari 31097581aa ms-inline-asm: Scope inline asm labels to functions
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.

Ehsan Akhgari 2f93b448a8 clang-cl: Merge adjacent single-line __asm blocks
Summary:
This patch extends the __asm parser to make it keep parsing input tokens
as inline assembly if a single-line __asm line is followed by another line
starting with __asm too.  It also makes sure that we correctly keep
matching braces in such situations by separating the notions of how many
braces we are matching and whether we are in single-line asm block mode.

Dmitri Gribenko fc13b8baf1 MS inline asm: When LLVM called back to Clang to parse a name and do name
lookup, if parsing failed, we did not restore the lexer state properly, and
eventually crashed.  This change ensures that we always consume all the tokens
from the new token stream we started to parse the name from inline asm.

Chad Rosier 709863514e Temporarily XFAIL this test; the compiler will segfault if the target-specific
