Log:
rs6000: Disable shrink-wrap-separate for abi=spe (PR78168)

With the SPE ABI, if we wrap GPRs we need to handle the upper half of the
extended 64-bit registers as well, which we cannot easily do.  So, this
patch disables separate shrink-wrapping for the SPE ABI.

	PR target/78168
	* config/r6000/rs6000.c (rs6000_get_separate_components): Return
	NULL if TARGET_SPE_ABI.
