TableGen had been generating a different name for an anonymous multiclass's NAME for every def in the multiclass. This had an unfortunate side effect: it was impossible to reference one def within the multiclass from another (in the parameter list, for example). By making sure we only generate an anonymous name once per multiclass (which, as it turns out, requires only changing the name parameter to reference type), we can now concatenate NAME within the multiclass with a def name in order to generate a reference to that def. This does not matter so much, in and of itself, but is necessary for a follow-up commit that will fix variable capturing in implicit anonymous multiclass defs (and that is important). git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@198340 91177308-0d34-0410-b5e6-96231b3b80d8
