There is TARGET_USE_INCDEC flag that already implements your suggestion.
>From predicates.md:
/* On Pentium4, the inc and dec operations causes extra dependency on flag
registers, since carry flag is not set. */
if (!TARGET_USE_INCDEC && !optimize_size)
If used elsewhere, this flag should perhaps be renamed to proposed
TARGET_PARTIAL_FLAG_REG_STALL.
