sys/sdt.h fp constraints cont'd, x86-64 edition
    
    It appears that various versions of gcc continue to show signs of
    confusion at our newly offered asm-operand alternatives for floating
    point sdt.h marker parameters.
    
    e.g., https://bugzilla.redhat.com/show_bug.cgi?id=2028798
    
    We may need to restore previous constraints broadly, forcing the
    compiler to plop floating point parameters into integer storage.
