[m-dev.] timings for lco with current compiler

[Julien Fischer]

Hi,

As I mentioned on mercury-users, here are the timings for the speedtest
benchmark with the current compiler (run on goliath).  The benchmark
was run in both the asm_fast.gc and hlc.gc grades, with and without
intermodule optimisation and lco and at -O2,-O3,-O4 and -O5.
(A caveat: since bug #57 has yet to be fixed, some tail call
opportunities created by lco may not be taken advantage of.)


Another point of interest here is the performance of the
compiler in hlc.gc at -O4.

Julien.
