reload.c (reg_overlap_mentioned_for_reload_p): When looking at a PLUS in X...

* reload.c (reg_overlap_mentioned_for_reload_p):
When looking at a PLUS in X, avoid spuriously returning nonzero
when IN is a REG or another simple PLUS, or a MEM containing one.

* loop.c (loop_invariant_p): Amend comment about where new registers
might come from.
