  [BOLT] Clean up jump table handling in non-reloc mode. NFCI (#119614)

This change affects non-relocation mode only. Prior to having
CheckLargeFunctions pass, we could have emitted code for functions that
was discarded at the end due to size limitations. Since we didn't know
at the time of emission if the code would be discarded or not, we had to
emit jump tables in separate sections and handle them separately.
However, now we always run CheckLargeFunctions and make sure all emitted
code is used. Thus, we can get rid of the special jump table handling.
