    testsuite: Fix up FAILs in gfortran testsuite with -fcompare-debug [PR94280]
    
    These 3 tests use compiler_options() function,
    which is inherently incompatible with -fcompare-debug compilation, as it
    emits into a string literal in the assembly the exact f951 command line
    options, which differs between the two compilations with -fcompare-debug,
    where one has -gtoggle and -fcompare-debug-second options added and
    different -fdump-final-insns= option argument.
    
    The following patch adds dg-skip-if directives, so that these tests are
    ignored during
    make check-gfortran RUNTESTFLAGS='--target_board=unix/-fcompare-debug'
