    Partially revert ac76bc1145dd because it is no longer necessary
    
    In ac76bc1145dd, I added a few volatiles to work around ctrig_test
    failures with {inf,inf}. This is not necessary anymore now, since in
    3b00222f156d we added -fp-exception-behavior=maytrap for clang >= 10 in
    libm's Makefile. (The flag tells clang to use stricter floating point
    semantics, which libm depends on.)
    
    PR:             244732, 254911
    Fixes:          ac76bc1145dd
    
    (cherry picked from commit e2157cd0000f6dbb6465d7a885f2dcfd4d3596cb)
