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.

Reid Kleckner 9b3e3dfc54 MS inline asm: Allow __asm blocks to set a return value
If control falls off the end of a function after an __asm block, MSVC
assumes that the inline assembly filled the EAX and possibly EDX
registers with an appropriate return value. This functionality is used
in inline functions returning 64-bit integers in system headers, so we
need some amount of compatibility.

This is implemented in Clang by adding extra output constraints to every
inline asm block, and storing the resulting output registers into the
return value slot. If we see an asm block somewhere in the function
body, we emit a normal epilogue instead of marking the end of the
function with a return type unreachable.

Normal returns in functions not using this functionality will overwrite
the return value slot, and in most cases LLVM should be able to
eliminate the dead stores.

Fixes PR17201.

Reid Kleckner e2d6429493 MS inline asm: Tests for r214550
These tests seem like an exception to the rule against assembly emitting
tests in clang.  I made an LLVM side change that can only be tested by
setting up the inline assembly machinery that is only implemented by
Clang.

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.

Reid Kleckner 185940a765 MS asm: Filter out fpsw clobbers
When parsing MS inline assembly, we note that fpsw is an implicit def of
most x87 FP operations, and add it to the clobber list.  However, we
don't recognize fpsw as a gcc register name, and we assert.  Clang
always adds an fpsr clobber, which means the same thing to LLVM, so we
can just use that.

This test case was broken by my LLVM change r196939.
