LoongArch: Assign DWARF register numbers to register aliases
.cfi directives only support the use of register numbers and not
register names or aliases.
This commit adds support for 4 formats, for example:
.cfi_offset r1, 8
.cfi_offset ra, 8
.cfi_offset $r1,8
.cfi_offset $ra,8
The above .cfi directives are equivalent and all represent dwarf
register number 1.
Display register aliases as specified in the psABI during disassembly.
