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.
