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.

Fix for the following bug in AVX codegen for double-to-int conversions:
. "fptosi" and "fptoui" IR instructions are defined with round-to-zero rounding mode.
. Currently for AVX mode for <4xdouble> and <8xdouble> the "VCVTPD2DQ.128" and "VCVTPD2DQ.256" instructions are selected (for .fp_to_sint. DAG node operation ) by AVX codegen. However they use round-to-nearest-even rounding mode.
. Consequently, the conversion produces incorrect numbers.
The fix is to replace selection of VCVTPD2DQ instructions with VCVTTPD2DQ instructions. The latter use truncate (i.e. round-to-zero) rounding mode.
As .fp_to_sint. DAG node operation is used only for lowering of "fptosi" and "fptoui" IR instructions, the fix in X86InstrSSE.td definition file doesn.t have an impact on other LLVM flows.
The patch includes changes in the .td file, LIT test for the changes and a fix in a legacy LIT test (which produced asm code conflicting with LLVN IR spec).

Revert a tiny bit of r148553 which extended LLVM's function attributes
to 64-bits, and added a new attribute in bit #32. Specifically, remove
this new attribute from the enum used in the C API. It's not yet clear
what the best approach is for exposing these new attributes in the
C API, and several different proposals are on the table. Until then, we
can simply not expose this bit in the API at all.
Also, I've reverted a somewhat unrelated change in the same revision
which switched from "1 << 31" to "1U << 31" for the top enum. While "1
<< 31" is technically undefined behavior, implementations DTRT here.
However, MS and -pedantic mode warn about non-'int' type enumerator
values. If folks feel strongly about this I can put the 'U' back in, but
