This commit modifies the existing call lowering functions to be used as the FastLowerCall and FastLowerIntrinsicCall target-hooks instead. This enables patchpoint intrinsic lowering for AArch64. This fixes <rdar://problem/17733076> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@213704 91177308-0d34-0410-b5e6-96231b3b80d8
