Marcin Koscielnicki 60b3cbe095 [MSan] [AArch64] Fix vararg helper for >1 or non-int fixed arguments. 
This fixes http://llvm.org/PR27646 on AArch64.

There are three issues here:

- The GR save area is 7 words in size, instead of 8.  This is not enough
  if none of the fixed arguments is passed in GRs (they're all floats or
  aggregates).
- The first argument is ignored (which counteracts the above if it's passed
  in GR).
- Like x86_64, fixed arguments landing in the overflow area are wrongly
  counted towards the overflow offset.

Adhemerval Zanella d2b10c5e9a [sanitizer] [msan] VarArgHelper for AArch64 
This patch add support for variadic argument for AArch64.  All the MSAN
unit tests are not passing as well the signal_stress_test (currently
set as XFAIl for aarch64).
