Change the fast-isel-abort option from bool to int to enable "levels" Summary: Currently fast-isel-abort will only abort for regular instructions, and just warn for function calls, terminators, function arguments. There is already fast-isel-abort-args but nothing for calls and terminators. This change turns the fast-isel-abort options into an integer option, so that multiple levels of strictness can be defined. This will help no being surprised when the "abort" option indeed does not abort, and enables the possibility to write test that verifies that no intrinsics are forgotten by fast-isel.

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 target-dependent instruction selection for Add/Sub. There is already target-dependent instruction selection support for Adds/Subs to support compares and the intrinsics with overflow check. This takes advantage of the existing infrastructure to also support Add/Sub, which allows the folding of immediates, sign-/zero-extends, and shifts. This fixes rdar://problem/18207316. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@217007 91177308-0d34-0410-b5e6-96231b3b80d8
