This was failng on any pre-assigned copy to the VCC bank. This is something of a workaround for the default implementation in getInstrMappingImpl, and how it treats copy-like operations in general. Copy-like operations are considered to only have one result register bank, rather than separate banks for each source like a normal instruction. To avoid potentially mishandling reg_sequence with impossible operand combinations, the generic implementation errors on impossible costs. If the bank was already assigned, is treated it as-if it were an unsatisfiable REG_SEQUENCE mapping. We really don't get any value from any of what getInstrMappingImpl tries to do for copies, so just directly emit the simple mapping we really want.
