For those who are interested, I've included the output of
tools/speed_summary for the batch that Julien was referring to below. 
It shows that both hlc.gc and hl.gc run slightly faster than
asm_fast.gc.

EXTRA_MCFLAGS =
GRADE = none.gc
mercury_compile.01 average of 6 with ignore=1     60.38
EXTRA_MCFLAGS =
GRADE = reg.gc
mercury_compile.02 average of 6 with ignore=1     60.74
EXTRA_MCFLAGS =
GRADE = asm_fast.gc
mercury_compile.03 average of 6 with ignore=1     22.37
EXTRA_MCFLAGS =
GRADE = hlc.gc
mercury_compile.04 average of 6 with ignore=1     21.91
EXTRA_MCFLAGS =
GRADE = hl.gc
mercury_compile.05 average of 6 with ignore=1     22.08
EXTRA_MCFLAGS =
GRADE = hlc.par.gc
mercury_compile.06 average of 6 with ignore=1     25.71
EXTRA_MCFLAGS =
GRADE = hl.par.gc
mercury_compile.07 average of 6 with ignore=1     25.36

I've just started building a new batch using --use-local-vars, and
will have some results soon.

Regards,
Sam.
