    LoongArch: testsuite: Add compilation options to the regname-fp-s9.c.
    
    When the value of the macro DEFAULT_CFLAGS is set to '-ansi -pedantic-errors',
    regname-s9-fp.c will test to fail. To solve this problem, add the compilation
    option '-Wno-pedantic -std=gnu90' to this test case.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/loongarch/regname-fp-s9.c: Add compilation option
            '-Wno-pedantic -std=gnu90'.
