[AArch64][AsmParser] NFC: Cleanup parsing of scalar registers.
Summary:
- Renamed tryParseRegister to tryParseScalarRegister, which
now returns an OperandMatchResultTy.
- Moved matching of certain aliases into matchRegisterNameAlias.
- Changed type of most 'Reg' variables to 'unsigned'.
This is patch [1/4] in a series to add assembler/disassembler support for
SVE's contiguous LD1 (scalar+scalar) instructions:
