[PATCH] AArch64 Neon Misc Scalar Arithmetic Instructions

[mcrosier at codeaurora.org]

All,
The attached patches contain clang front-end and LLVM back-end code
changes to add support for the following NEON scalar arithmetic
instructions:

-Signed saturating doubling multiply high half - SQDMULH
-Signed saturating rounding doubling multiply high half - SQRDMULH
-Floating-point multiply extended - FMULX
-Floating-point reciprocal step - FRECPS
-Floating-point reciprocal square root step - FRSQRTS

Please have a look!
