Before LL, instrument outstanding helper calls.

Callgrind, Cachegrind, and Lackey call
helpers for memory accesses in bunches, to reduce
register save/restore overhead (and merge load/store
within same instruction into a "modify" event).

The calls should not be done within a RMW section
enclosed by LL/SC instructions, as this reduces the
chance of SC to succeed, and can result in hangs.
For Callgrind, this definitly helped MIPS, and was
committed in r13136. Do the same for Cachegrind/Lackey.
