[m-rev.] [PATCH] Make module_qualify_items_loop tail recursive again with LCMC.

[Peter Wang]

The predicate module_qualify_items_loop was moved into a new module in
commit df794c259a6a93eaaedff765e54b339f33d11631 but the option required
for it to be tail recursive was not transferred to the new module.

compiler/Mercury.options:
	Transfer --optimize-constructor-last-call to the new module
	containing module_qualify_items_loop.
