Fix recent bug in canonicalize_comparison (PR87026)
The new code testing which way a comparison is best expressed creates
a pseudoregister (by hand) and creates some insns with that. Such
insns will no longer recog() when pseudo-registers are no longer
aloowed (after reload). But we have an ifcvt pass after reload (ce3).
This patch simply returns if we cannot create pseudos.
PR rtl-optimization/87026
* expmed.c (canonicalize_comparison): If we can no longer create
pseudoregisters, don't.
