re PR bootstrap/91580 (i686-{darwin, linux} bootstrap fails after r274926)

PR bootstrap/91580
* config/i386/i386-features.c (general_scalar_chain::convert_insn):
Do not emit scalar copies for debug-insns, instead replace
their uses with the reg copy used in the chain or reset them
if there is a reaching definition outside of the chain as well.
