LoongArch: gas: add support using constant variable in instructions.

        Instructions that can load immediate support using constant
        variable like ".equ var, 123    li.w/d resgister, var".

gas/
        * config/loongarch-parse.y
        * config/tc-loongarch.c

        Add four testcases.One is a program using constant variable,
        one test using label is unsupported, and another two test
        almost instructions that can load immediate.
