into T) when no return values are actually dead.

nothing was changed. This should catch subtle changes in function type that are

Recommit r52459, rewriting of the dead argument elimination pass.
...
This is a fixed version that no longer uses multimap::equal_range, which
resulted in a pointer invalidation problem.
Also, DAE::InspectedFunctions was not really necessary, so it got removed.
Lastly, this version no longer applies the extra arg hack on functions who did
not have any arguments to start with.

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.
