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.

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).

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.

re-use that for SlotIndexes. This way other users who want half-open

[ASan] Fix lifetime intrinsics handling. Now for each intrinsic we check if it describes one of 'interesting' allocas. Assume that allocas can go through casts and phi-nodes before apperaring as llvm.lifetime arguments

and mixing the two types creates horrible code. This commit optimizes
some of the transition sequences.

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.

Refactor DAGCombinerInfo. Change the different booleans that indicate if we are before or after different runs of DAGCo, with the CombineLevel enum.
Also, added a new API for checking if we are running before or after the LegalizeVectorOps phase.

Move single letter 'P' prefix out of multiclass now that tablegen allows defm to start with #NAME. This makes instruction names more searchable again.

The language linkage of redeclarations must match. GCC was already reporting
an error for this.
