New Revision: 113388

URL: http://llvm.org/viewvc/llvm-project?rev=113388&view=rev
Log:
Add intrinsic forms of mmx<->sse conversions.  Notes:
Omission of memory form of PI2PD is intentional; this
does not use an MMX register and does not put the chip
into MMX mode (PI2PS, oddly enough, does).
Operands of PI2PS follow the gcc builtin, not Intel.
