Revert support for insertvalue and extractvalue instructions for the moment.
...
GVN expects that all inputs which to an instruction fall somewhere in the value
hierarchy, which isn't true for these.

Fix a bug with <8 x i16> shuffle lowering on X86 where parts of the
...
shuffle could be skipped. The check is invalid because the loop index i
doesn't correspond to the element actually inserted. The correct check is
already done a few lines earlier, for whether the element is already in
the right spot, so this shouldn't have any effect on the codegen for
code that was already correct.

dependencies between return values and/or arguments. Also make the handling of
