[AARCH64] Enable AARCH64 lit tests on windows dev machines As discussed on PR27654, this patch fixes the triples of a lot of aarch64 tests and enables lit tests on windows This will hopefully help stop cases where windows developers break the aarch64 target Differential Revision: https://reviews.llvm.org/D22191 llvm-svn: 275973

Fix for codegen bug that could cause illegal cmn instruction generation In rare cases the dead definition elimination pass code can cause illegal cmn instructions when it replaces dead registers on instructions that use unmaterialized frame indexes. This patch disables the dead definition optimization for instructions which include frame index operands. rdar://16438284 llvm-svn: 206208

ARM64: print canonical syntax for add/sub (imm) instructions. Since these instructions only accept a 12-bit immediate, possibly shifted left by 12, the canonical syntax used by the architecture reference manual is "#N {, lsl #12 }". We should accept an immediate that has already been shifted, (e.g. Also, print a comment giving the full addend since it can be helpful. llvm-svn: 207633
