Andrea Di Biagio 9a85b7abe0 [x86] Fix AVX maskload/store intrinsic prototypes. 
The mask value type for maskload/maskstore GCC builtins is never a vector of
packed floats/doubles.

This patch fixes the following issues:
1. The mask argument for builtin_ia32_maskloadpd and builtin_ia32_maskstorepd
   should be of type llvm_v2i64_ty and not llvm_v2f64_ty.
2. The mask argument for builtin_ia32_maskloadpd256 and
   builtin_ia32_maskstorepd256 should be of type llvm_v4i64_ty and not
   llvm_v4f64_ty.
3. The mask argument for builtin_ia32_maskloadps and builtin_ia32_maskstoreps
   should be of type llvm_v4i32_ty and not llvm_v4f32_ty.
4. The mask argument for builtin_ia32_maskloadps256 and
   builtin_ia32_maskstoreps256 should be of type llvm_v8i32_ty and not
   llvm_v8f32_ty.

Elena Demikhovsky 824eed70a6 Passing AVX 256-bit structures in Win64 was wrong. 
Fixed Win64 calling conventions.

Jakob Stoklund Olesen fc9dce25f7 Handle call-clobbered ymm registers on Win64. 
The Win64 calling convention has xmm6-15 as callee-saved while still
clobbering all ymm registers.

Add a YMM_HI_6_15 pseudo-register that aliases the clobbered part of the
ymm registers, and mark that as call-clobbered.  This allows live xmm
registers across calls.

This hack wouldn't be necessary with RegisterMask operands representing
the call clobbers, but they are not quite operational yet.
