5bdf397e25 Synchronize VEX JIT encoding code with the MCJIT version. Fix a bug in the MCJIT code where CurOp was being incremented even if the operand it was pointing at wasn't used. Maybe only matters if there are any EVEX_K instructions that aren't VEX_4V.

ec7b5e9290 In LLVM FMA3 operands are dst, src1, src2, src3, however dst is not encoded as it is always src1. This was causing the encoding of the operands to be off by one.

33b5fe7f16 Rename mattr names for AVX-512 to from avx-512 -> avx512f, avx-512-pfi -> av512pf, avx-512-cdi -> avx512cd, avx-512-eri->avx512er. This matches better with official docs and what gcc patches appearto be using. I didn't touch the has* functions or the feature flag names to avoid change the td and lowering file while commits are still happening.

d113448c1d Refactor isInTailCallPosition handling 
This change came about primarily because of two issues in the existing code.
Niether of:

define i64 @test1(i64 %val) {
  %in = trunc i64 %val to i32
  tail call i32 @ret32(i32 returned %in)
  ret i64 %val
}

define i64 @test2(i64 %val) {
  tail call i32 @ret32(i32 returned undef)
  ret i32 42
}

should be tail calls, and the function sameNoopInput is responsible. The main
problem is that it is completely symmetric in the "tail call" and "ret" value,
but in reality different things are allowed on each side.

For these cases:
1. Any truncation should lead to a larger value being generated by "tail call"
   than needed by "ret".
2. Undef should only be allowed as a source for ret, not as a result of the
   call.

Along the way I noticed that a mismatch between what this function treats as a
valid truncation and what the backends see can lead to invalid calls as well
(see x86-32 test case).

This patch refactors the code so that instead of being based primarily on
values which it recurses into when necessary, it starts by inspecting the type
and considers each fundamental slot that the backend will see in turn. For
example, given a pathological function that returned {{}, {{}, i32, {}}, i32}
we would consider each "real" i32 in turn, and ask if it passes through
unchanged. This is much closer to what the backend sees as a result of
ComputeValueVTs.

Aside from the bug fixes, this eliminates the recursion that's going on and, I
believe, makes the bulk of the code significantly easier to understand. The
trade-off is the nasty iterators needed to find the real types inside a
returned value.
