- Teach SSEDomainFix to switch between different levels of AVX instructions. Here we guess that AVX will have domain issues, so just implement them for consistency  and in the future we remove if it's unnecessary.
- Make foldMemoryOperandImpl aware of 256-bit zero vectors folding and support the 128-bit counterparts of AVX too.
- Make sure MOV[AU]PS instructions are only selected when SSE1 is enabled, and duplicate the patterns to match AVX.
- Add a testcase for a simple 128-bit zero vector creation.

term goal here is to be able to match enough of vector_shuffle and build_vector
so all avx intrinsics which aren't mapped to their own built-ins but to
shufflevector calls can be codegen'd. This is the first (baby) step, support
building zeroed vectors.

instructions onto the target specific parser, which can do a better job.

target specific parsers can adapt the TargetAsmParser to this.

When a register is defined by a partial load:

  %reg1234:sub_32 = MOV32mr <fi#-1>; GR64:%reg1234

That load cannot be folded into an instruction using the full 64-bit register.
It would become a 64-bit load.

This is related to the recent change to have isLoadFromStackSlot return false on
a sub-register load.

avoids trouble if the return type of TD->getPointerSize() is
changed to something which doesn't promote to a signed type,
and is simpler anyway.

Also, use getCopyFromReg instead of getRegister to read a
physical register's value.

Apply the same approach of SSE4.1 ptest intrinsics but
create a new x86 node "testp" since AVX introduces
vtest{ps}{pd} instructions which set ZF and CF depending
on sign bit AND and ANDN of packed floating-point sources.

This is slightly different from what the "ptest" does.
Tests comming with the other 256 intrinsics tests.

Next time the build is broken due to wrong library dependencies, just
try building again (if you are on some Unix and are building all LLVM
targets) or ask someone to commit the regenerated LLVMLibDeps.cmake.
