Description
The support for TEMP operands in the adlc has some sanity checks that require TEMPs to come before KILLs since kill normally aren't really uses.  This simplifies some of the logic for mapping between operands and inputs.  The existing logic is being too strict since it complains about USE_KILLs instead of just raw KILLs.  The code should be modified to ignore USE_KILLs.
