[FastISel][AArch64] Add select folding support for the XALU intrinsics. This improves the code generation for the XALU intrinsics when the condition is feeding a select instruction. This also updates and enables the XALU unit tests for FastISel. This fixes <rdar://problem/17831117>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214350 91177308-0d34-0410-b5e6-96231b3b80d8

ARM64: initial backend import This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205090 91177308-0d34-0410-b5e6-96231b3b80d8

[FastISel][AArch64] Add select folding support for the XALU intrinsics. This improves the code generation for the XALU intrinsics when the condition is feeding a select instruction. This also updates and enables the XALU unit tests for FastISel. This fixes <rdar://problem/17831117>. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@214350 91177308-0d34-0410-b5e6-96231b3b80d8

ARM64: initial backend import This adds a second implementation of the AArch64 architecture to LLVM, accessible in parallel via the "arm64" triple. The plan over the coming weeks & months is to merge the two into a single backend, during which time thorough code review should naturally occur. Everything will be easier with the target in-tree though, hence this commit. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@205090 91177308-0d34-0410-b5e6-96231b3b80d8
