This reduces the size of the StackHandler by yet another word. We no
longer need to keep track of the frame pointer, as the stack walk will
be able to recalculate it.

Contribution of PowerPC port (continuation of 422063005, 817143002,
866843003, and 901083004. This patch updates the ppc directories
to make them current with changes in common code, removes the
optimization to use the ool constant pool, and excludes tests that
don't pass under the ppc simulator given a 240s timeout.

Subsequent patches will cover:
   - remaining optimizations for PPC
   - remaining AIX changes not resolved by 4.8 compiler (4.8 is only recently available for AIX)
   - incremental updates required to ppc directories due to platform specific changes made
    in google repos while we complete the above steps.
