    testsuite, c++, x86, Darwin: Adjust func body scan tests for Darwin ABI/asm.
    
    In these cases, we need to add USER_LABEL_PREFIX or a second regex to cater for
    the Darwin ABI and Mach-O syntax.
    
    gcc/testsuite/ChangeLog:
    
            * g++.target/i386/cf_check-4.C: Support Darwin ABI/Mach-O syntax.
            * g++.target/i386/memset-pr108585-1a.C: Likewise.
            * g++.target/i386/memset-pr108585-1b.C: Likewise.
