cntlz is the old POWER mnemonic. cntlzw is the PowerPC mnemonic. This change fixes an issue when -no-integrated-as: The opcode cntlz is unrecognized by gas Alias the POWER mnemonic cntlz[.] to the PowerPC mnemonic cntlzw[.] This is done for because the POWER cntlz mnemonic has be used by LLVM for a very long time. We need to make sure that assembly programs that are using the cntlz[.] do not break with this change. Change PowerPC tests to reflect the insn change from cntlz to cntlzw. Add assembly test to verify cntlz[.] is encoded correctly. Patch by Tom Rix! git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@251489 91177308-0d34-0410-b5e6-96231b3b80d8
