[cfe-commits] [PATCH] AArch64 backend: Clang changes

[Tim Northover]

  This update should have the following differences:

  + Use normal LLVM instructions rather than a special vfms intrinsic to implement vfms NEON intrinsic (Renato)
  + Improved function to mangle NEON types for C++ (John McCall)
  + Various coding style and other semantically null improvements (also John).
  + NEON vectors of double are still diagnosed on AArch32 now (John).

  In addition, the change of poly8_t and poly16_t to unsigned types is present in this patch, though that issue will be largely settled in a separate thread. Once the issue is decided it will either disappear completely or be converted into a target-dependent test.
