The implicit immediate 0 forms are assembly aliases, not distinct instruction encodings. Fix the initial implementation introduced in r198914 to an alias to avoid two separate instruction definitions for the same encoding. An InstAlias is insufficient in this case as the necessary due to the need to add a new additional operand for the implicit zero. By using the AsmPsuedoInst, fall back to the C++ code to transform the instruction to the equivalent _POST_IMM form, inserting the additional implicit immediate 0. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@199032 91177308-0d34-0410-b5e6-96231b3b80d8
