    LoongArch: testsuite: Disable stack protector for some tests
    
    Stack protector will affect stack layout and break the expectation of
    these tests, causing test failures if GCC is configured with
    --enable-default-ssp.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/loongarch/prolog-opt.c (dg-options): Add
            -fno-stack-protector.
            * gcc.target/loongarch/stack-check-cfa-1.c (dg-options):
            Likewise.
            * gcc.target/loongarch/stack-check-cfa-2.c (dg-options):
            Likewise.
