gas: xtensa: speed up find_trampoline_seg

find_trampoline_seg takes noticeable time when assembling source with
many sections. Cache the result of the most recent search and check it
first. No functional changes.

* config/tc-xtensa.c (find_trampoline_seg): Add static variable
that caches the result of the most recent search.
