LoongArch: gas: Add support for tls le relax.
Add tls le relax related relocs support and testsuites in gas.
The main test is three new relocation items,
R_LARCH_TLS_LE_ADD_R, R_LARCH_TLS_LE_HI20_R,
R_LARCH_TLS_LE_LO12_R can be generated properly
and tls le insn format check.
gas/ChangeLog:
* config/tc-loongarch.c:
(loongarch_args_parser_can_match_arg_helper): Add support for relax.
* gas/testsuite/gas/loongarch/reloc.d: Likewise.
* gas/testsuite/gas/loongarch/reloc.s: Likewise.
* gas/testsuite/gas/loongarch/loongarch.exp: Likewise.
* gas/testsuite/gas/loongarch/tls_le_insn_format_check.s: New test.
