Subject: Don't skip the CopyMI when removing kill markers.
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=82fd3f3d3ad44b7e3d0e7efc51a6498731746f79

Don't skip the CopyMI when removing kill markers.
This should have no effect on generated code, but makes the intermediate state
of the coalescer more sane.
