[clang] Constexpr for __builtin_shufflevector and __builtin_convertvector
Summary:
This patch adds constexpr support for __builtin_shufflevector
and __builtin_convertvector.
A small oddity encountered was that the arg to the intrinsics may be an
lvalue without any sort of implicit cast of any kind. I solved this
through the EvaluateVectorOrLValue function, which treats the lvalue as
if it was in an rvalue cast, which gets me the desired vector.
