Commit in the name of: Coby Tayree 

1.'v' constraint for (x86) non-avx arch imitates the already implemented 'x' constraint, i.e. allows XMM{0-15} & YMM{0-15} depending on the apparent arch & mode (32/64).
2.for the avx512 arch it allows [X,Y,Z]MM{0-31} (mode dependent)

We have a loop-rerolling optimization which can be enabled by using
-freroll-loops. While sometimes loops are hand-unrolled for performance
reasons, when optimizing for size, we should always undo this manual
optimization to produce smaller code (our optimizer's unroller will still
unroll the rerolled loops if it thinks that is a good idea).

This is obviously wrong -- if we do this, then all compiles will pick up
these wrappers, which is not what we want.

We do this by wrapping <complex> and <algorithm>.

Summary:
Currently we declare our inline __device__ math functions in namespace
std.  But libstdc++ and libc++ declare these functions in an inline
namespace inside namespace std.  We need to match this because, in a
later patch, we want to get e.g. <complex> to use our device overloads,
and it only will if those overloads are in the right inline namespace.

Summary:
These cause us to consider all functions in-between to be __host__
__device__.

You can nest these pragmas; you just can't have more 'end's than
'begin's.

The core of the change is supposed to be NFC, however it also fixes
what I believe was an undefined behavior when calling:

 va_start(ValueArgs, Desc);

with Desc being a StringRef.

Summary:
Move CheckCUDACall from ActOnCallExpr and BuildDeclRefExpr to
DiagnoseUseOfDecl.  This lets us catch some edge cases we were missing,
specifically around class operators.

This necessitates a few other changes:

 - Avoid emitting duplicate deferred diags in CheckCUDACall.

   Previously we'd carefully placed our call to CheckCUDACall such that
   it would only ever run once for a particular callsite.  But now this
   isn't the case.

 - Emit deferred diagnostics from a template
   specialization/instantiation's primary template, in addition to from
   the specialization/instantiation itself.  DiagnoseUseOfDecl ends up
   putting the deferred diagnostics on the template, rather than the
   specialization, so we need to check both.

This is the primary suspect for causing the msvc crash, now that vector of
smart pointers was proven to be safe. Probably the default {}-initializer
is the problem.

Make the -print-libgcc-file-name option print an appropriate compiler
runtime library, that is libgcc.a if gcc runtime is used
and an appropriate compiler-rt library if that runtime is used.

The main use for this is to allow linking executables built with
-nodefaultlibs (e.g. to avoid linking to the standard C++ library) to
the compiler runtime library, e.g. using:

  clang++ ... -nodefaultlibs $(clang++ ... -print-libgcc-file-name)

in which case currently a program built like this linked to the gcc
runtime unconditionally. The patch fixes it to use compiler-rt libraries
instead when compiler-rt is the active runtime.

CheckSingleAssignmentConstraints. These no longer produce ExprError() when they
have not emitted an error, and reliably inform the caller when they *have*
emitted an error.

This fixes some serious issues where we would fail to emit any diagnostic for
invalid code and then attempt to emit code for an invalid AST, and conversely
some issues where we would emit two diagnostics for the same problem.
