LoongArch: Use ABI names of registers where appropriate
Some of the assembly in the LoongArch port seem to come from a
prehistoric time, when the assembler didn't even have support for the
ABI names we all come to know and love, thus used raw register numbers
which hampered readability.
The usages are found with a regex match inside arch/loongarch, then
manually adjusted for those non-definitions.
