[Bug middle-end/117352] switch bit test conversion makes comparison code worse

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=117352 --- Comment #2 from Andrew Pinski --- But note not all targets support all comparisons with ccmp (though I think for integer both x86_64 and aarch64 supports all, it is float comparisons where TARGET_GEN_CCMP_FIRST/TARGET_GEN_CCMP_NEXT can fail)
