This adds debug tracing to the table-generated assembly instruction matcher, enabled by the -debug-only=asm-matcher option. The changes in the target AsmParsers are to add an MCInstrInfo reference under a consistent name, so that we can use it from table-generated code. This was already being used this way for targets that use deprecation warnings, but 5 targets did not have it, and Hexagon had it under a different name to the other backends. llvm-svn: 315445
