As destination k0 is allowed but not as predicate/writemask.
I also modified the test to allow checking of error messages by the assembler.
I applied a similar approach to the test ret.s in the same directory.

This new multiclass, avx512_perm_table_3src derives from the current one and
provides the Pat<>. The next patch will add another Pat<> that uses the
writemask.
Note that I dropped the type annotation from the intrinsic call, i.e.: (v16f32
VR512:$src1) -> R512:$src1. I think that this should be fine (at least many
intrinsic calls don't provide them) and it greatly reduces the number of
template arguments.

This includes assembler and codegen support (see the new tests in
avx512-encodings.s and avx512-shuffle.ll).

For now I only updated the _alt variants. The main variants are used by
codegen and that will need a bit more work to trigger.

Adding a writemask variant would require a third asm string to be passed to
the template. Generate the AsmString in the template instead.
No change in X86.td.expanded.

For now I used a separate template for these sub-vector/tuple broadcasts
rather than sharing the mem variants with avx512_int_broadcast_rm.

The *_alt defs for vcmp are used by the InstParser (the asm string in the main
def is used by the InstPrinter) . The former was accepting vector registers
as destination rather than mask registers.

Note that I followed the AVX2 convention here and didn't add LLVM intrinsics
for stores. These can be generated with the nontemporal hint on LLVM IR
stores (see new test). The GCC builtins are lowered directly into nontemporal
stores.

Use the max 64-bit element size with EVEX_CD8. This should work since element
size is ignored for a full-vector access (FVM).

1) Changed gather and scatter intrinsics. Now they are aligned with GCC built-ins. There is no more non-masked form. Masked intrinsic receives -1 if all lanes are executed.
2) I changed the function that works with intrinsics inside X86ISelLowering.cpp. I put all intrinsics in one table. I did it for INTRINSICS_W_CHAIN and plan to put all intrinsics from WO_CHAIN set to the same table in order to avoid the long-long "switch". (I wanted to use static map initialization that allowed by C++11 but I wasn't able to compile it on VS2012).
3) I added gather/scatter prefetch intrinsics.
4) I fixed MRMm encoding for masked instructions.

Summary:
The INSERTPS pattern fragment was called insrtps (mising 'e'), which
would make it harder to grep for the patterns related to this instruction.
Renaming it to use the proper instruction name.

This should allow SSE instructions to be encoded correctly in 16-bit mode which r198586 probably broke.
