    check-function-bodies: Support "^[0-9]+:"
    
    While working on
    
    https://gcc.gnu.org/bugzilla/show_bug.cgi?id=120936
    
    I tried to use check-function-bodies to verify that label for mcount
    and __fentry__ is only generated by "-pg" if it is used by __mcount_loc
    section:
    
    1:      call    mcount
            .section __mcount_loc, "a",@progbits
            .quad 1b
            .previous
    
    Add "^[0-9]+:" to check-function-bodies to allow:
    
    1:      call    mcount
    
            PR testsuite/120881
            * lib/scanasm.exp (check-function-bodies): Allow "^[0-9]+:".
