[PATCH] D30491: [AArch64AsmParser] cleanup/rewrite of function parseSysAlias

This is a cleanup/rewrite of the parseSysAlias function. This was not using the tablegen instruction descriptions, but was “manually” matching the mnemonics and recreating the operands whereas all this information is already in tablegen, so all this code has been replaced with calls to lookupXYZByName tablegen calls.
