Move 64-bit multiplication to helper

We're right on the edge for supporting inline 64-bit arithmetic
with our current temp register pool allocation.  Moving 64-bit multiplication
out of line to sidestep the problem, and added some temp frees to
3-operand long ops.  In the latter case there was a potential problem
if the result long was located in a part of the frame not in the range
of a single base+displacement store.
