e3a9b4ce3a Fix a bunch more layering of CodeGen headers that are in Target
All these headers already depend on CodeGen headers so moving them into
CodeGen fixes the layering (since CodeGen depends on Target, not the
other way around).

b872fbbb3d [X86][DAG] Switch X86 Target to post-legalized store merge
Move store merge to happen after intrinsic lowering to allow lowered
stores to be merged.

Some regressions due in MergeConsecutiveStores to missing
insert_subvector that are addressed in follow up patch.

3f4f926b6a Rewrite areNonVolatileConsecutiveLoads to use BaseIndexOffset
Relanding after rewriting undef.ll test to avoid host-dependant
endianness.

As discussed in D34087, rewrite areNonVolatileConsecutiveLoads using
generic checks. Also, propagate missing local handling from there to
BaseIndexOffset checks.

Tests of note:

  * test/CodeGen/X86/build-vector* - Improved.
  * test/CodeGen/BPF/undef.ll - Improved store alignment allows an
    additional store merge

  * test/CodeGen/X86/clear_upper_vector_element_bits.ll - This is a
    case we already do not handle well. Here, the DAG is improved, but
    scheduling causes a code size degradation.

8ebfef5200 [DAG] Fold FrameIndex offset into BaseIndexOffset analysis. NFCI.
Relanding after restricting equalBaseIndex to not erroneuosly consider
a FrameIndices stemming from alloca from being comparable as its
offset is set post-selectionDAG.

Pull FrameIndex comparision reasoning from DAGCombiner::isAlias to
general BaseIndexOffset.
