[LLVM] Remove unwanted --check-prefix=CHECK from unit tests. NFC. Summary: Removed unwanted --check-prefix=CHECK from numerous unit tests.

Add AArch64 as an experimental target. This patch adds support for AArch64 (ARM's 64-bit architecture) to LLVM in the "experimental" category. Currently, it won't be built unless requested explicitly. This initial commit should have support for: + Assembly of all scalar (i.e. non-NEON, non-Crypto) instructions (except the late addition CRC instructions). + CodeGen features required for C++03 and C99. + Compilation for the "small" memory model: code+static data < 4GB. + Absolute and position-independent code. + GNU-style (i.e. "__thread") TLS. + Debugging information. The principal omission, currently, is performance tuning. This patch excludes the NEON support also reviewed due to an outbreak of batshit insanity in our legal department. That will be committed soon bringing the changes to precisely what has been approved. Further reviews would be gratefully received. llvm-svn: 174054

[DAGCombiner] Attempt to mask vectors before zero extension instead of after. For cases where we TRUNCATE and then ZERO_EXTEND to a larger size (often from vector legalization), see if we can mask the source data and then ZERO_EXTEND (instead of after a ANY_EXTEND). This can help avoid having to generate a larger mask, and possibly applying it to several sub-vectors. (zext (truncate x)) -> (zext (and(x, m)) Includes a minor patch to SystemZ to better recognise 8/16-bit zero extension patterns from RISBG bit-extraction code. This is the first of a number of minor patches to help improve the conversion of byte masks to clear mask shuffles. Differential Revision: http://reviews.llvm.org/D11764 llvm-svn: 245160

AArch64: use 32-bit MOV rather than UBFX to truncate registers. It's potentially more efficient on Cyclone, and from the optimization guides & schedulers looks like it has no effect on Cortex-A53 or A57. In general you'd expect a MOV to be about the most efficient instruction with its semantics, even though the official "UXTW" alias is really a UBFX. llvm-svn: 243576
