Argument evaluation order is different between gcc and clang, so pull out
the Builder calls to make the generated IR independent of the host compiler's
argument evaluation order. Thanks to rnk for reminding me of this clang/gcc
difference.

EmitX86BuiltinExpr() emits all args into Ops at the beginning, so don't do that
work again.
This changes behavior: If e.g. ++a was passed as an arg, we incremented a twice
previously. This change fixes that bug.

r337619 added __shiftleft128 / __shiftright128 as functions in intrin.h.
Microsoft's STL plans on using these functions, and they're using intrin0.h
which just has declarations of built-ins to not pull in the huge intrin.h
header in the standard library headers. That requires that these functions are
real built-ins.

The tests that failed on a windows host have been fixed.
Original message:
Start setting dso_local for COFF.
With this there are still some GVs where we don't set dso_local
because setGVProperties is never called. I intend to fix that in
followup commits. This is just the bare minimum to teach
shouldAssumeDSOLocal what it should do for COFF.

It seems MS headers have started using __readgsqword, and since it's
used in a header that doesn't include intrin.h, we can't implement it as
an inline function anymore.
That was already the case for __readfsdword, which Saleem added support
for in r220859. This patch reuses that codegen to implement all of
__read[fg]s{byte,word,dword,qword}.
