MIPS: Second attempt at introducing a premonomorphic state in the call target caches.

MIPS: Second attempt at introducing a premonomorphic state in the call target caches.

Port: r19457 (9d8d5f3)

Original commit message:
This time we don't go through the premonomorphic state for
the Array call target caches to avoid losing information from
allocation sites that aren't only used once, but where the
resulting array is used heavily.

Patch from Kasper Lund <kasperl@chromium.org>;.

+1 for delay slot filling. (there is a similar pattern below at 3222, I'll
change that at commit, and hope I don't break anything ;-)
