I hit a bootstrap issue on powerpc64le-linux and it looks (still confirming)
that this is probably the patch that caused it, since we're ICEing in your new
combine_reload_insn() function.
I opened PR109179 for the ICE.

addkf3-sw.c: In function ‘__addkf3_sw’:
addkf3-sw.c:51:1: internal compiler error: RTL check: expected elt 3 type 'e'
or 'u', have '0' (rtx note) in PATTERN, at rtl.h:1509
