[mips] Added -mfp64 and -mfp32 options.
These options specify 64-bit FP registers and 32-bit FP registers respectively.
When using -mfp32, the FPU has 16x double-precision registers overlapping with
the 32x single-precision registers (each double-precision register overlaps
two single-precision registers).
When using -mfp64, the FPU has 32x double-precision registers overlapping with
the 32x single-precision registers (each double-precision register overlaps

Add support to the Clang driver for forwarding all of gfortran's flags
to GCC when asked to compile a fortran input.
This fixes a regression with essentially every Fortran compile since we
started rejecting unknown flags. Also moves a mis-classified gfortran
flag into the nicely documented set.

Add implementations of the MSVC barrier intrinsics
Summary:
These are deprecated in VS 2012 according to MSDN. They don't actually
compile down to any code. They prevent the compiler from reordering
memory accesses across the barrier, which is what a memory-clobbering
volatile asm does.

[analyzer] Don't draw edges to C++11 in-class member initializers.
Since these aren't lexically in the constructor, drawing arrows would
be a horrible jump across the body of the class. We could still do
better here by skipping over unimportant initializers, but this at least
keeps everything within the body of the constructor.

On 32 bit windows, mangle stdcall and fastcall decls in clang.
This removes the dependency on the llvm mangler doing it for us. In isolation,
the benefit is that the testing of what mangling is applied is all in one place:
(C, C++) X (Itanium, Microsoft) are all handled by clang.
This also gives me hope that in the future the llvm mangler (and llvm-ar) will
not depend on TargetMachine.

ms-compat: Fix taking the address of a member of a dependent base
If unqualified id lookup fails while parsing a class template with a
dependent base, clang with -fms-compatibility will pretend the user
prefixed the name with 'this->' in order to delay the lookup. However,
if there was a unary ampersand, Sema::ActOnDependentIdExpression() will
create a DependentDeclRefExpr, which is not what we wanted at all. Fix
this by building the CXXDependentScopeMemberExpr directly instead.
In order to be fully MSVC compatible, we would have to defer all
attempts at name lookup to instantiation time. However, until we have
real problems with system headers that can't be parsed, we'll put off
implementing that.
