Nadav Rotem 3da9ac72fa AVX: Move the ZEXT/ANYEXT DAGCo optimizations to the lowering of these optimizations. The old test cases still cover all of these lowering/optimizations. The single change that we have is that now anyext does not need to zero a register, because it does not use the exact code path as the zero_extend.

David Blaikie bf18725d11 Change this to an IR test instead of an assembly test (as per comment in r171134).
This makes the test not dependent on LLVM & won't vary/break based on LLVM
codegen related changes. Appropriately testing at the Clang level what was
fixed at the Clang level originally (in r124210).

Chandler Carruth 5826f96e51 Teach the extras repository to actually install the clang-format tool.
We should also install the clang-format.py script somewhere that makes
since for a Vim integration script. I don't know where that is though,
so just installing the binary for now. This is enough to let me use the
script from a checkout combined with the installed (and thus less likely
to crash or be slow) clang-format binary.

Nadav Rotem 2a054b4475 On AVX/AVX2 the type v8i1 is legalized to v8i16, which is an XMM sized
register. In most cases we actually compare or select YMM-sized registers
and mixing the two types creates horrible code. This commit optimizes
some of the transition sequences.

Nadav Rotem 8e5d80eba3 AVX/AVX2: Move the code that lowers vector-trunc from a DAGCo-hook to custom lowering hook.
The vector truncs were scalarized during LegalizeVectorOps, later vectorized again by some DAGCombine optimization
and finally, lowered by a dagcombing optimization. Now, they are properly lowered during LegalizeVectorOps.
No new testcase because the original testcases still work.
