    testsuite, x86: Match multi-word contants explictly.
    
    These tests now pass the function body scans on Darwin, but fail the
    scanasms for 16bye literals.  This because these scan separately for
    .long 0 appearing 3 times, with no constraint on sequence.  A bare
    .long 0 can also match other code (e.g. eh_frame literals) which leads
    to a fail everywhere on Darwin.
    
    Match these multi-word literals explicitly - which actually is better
    even on cfi-asm targets since it checks the literal and its memory
    order rather than the two parts independently.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.target/i386/builtin-copysign-2.c: Check 16 byte literal
            explicitly.
            * gcc.target/i386/builtin-copysign-3.c: Likewise.
            * gcc.target/i386/builtin-copysign-5.c: Likewise.
            * gcc.target/i386/builtin-fabs-1.c: Likewise.
