New Revision: 64621

URL: http://llvm.org/viewvc/llvm-project?rev=64621&view=rev
Log:
The LLVM IR intrinsics for movups, movupd, and movdqu will be going away,
as these operations can be represented with loads and stores with an
alignment of 1. This commit adds llvm-gcc support for translating the
GCC builtins to LLVM IR. This code is not used yet.
