During instruction selection, we rewrite the destination register class for MIMG instructions based on their writemasks. This creates machine verifier errors since the new register class does not match the register class in the MIMG instruction definition. We can avoid this by defining different MIMG instructions for each possible destination type and then switching to the correct instruction when we change the register class. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@192365 91177308-0d34-0410-b5e6-96231b3b80d8
