library/LIB_FLAGS.in:
library/Mercury.options:
Compile all modules in the library, not just a few, with
--optimize-constructor-last-call. I tried this last year, when
it yielded a slight slowdown on tools/speedtest; but now, it yields
a speedup of about 3.5%. The downside is not that important: a 2.8%
increase in the size of the archive file holding the Mercury standard
library.
