Nirav Dave d1b3f09faa [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.

Kenneth Uildriks 9f34406a90 x86 users can now return arbitrary sized structs. Structs too large to fit in return registers will be returned through a hidden sret parameter introduced during SelectionDAG construction.
