Sachin Monga 3051f3495c powerpc64le: _init/_fini file changes for ROP 
The ROP instructions were added in ISA 3.1 (ie, Power10), however they
were defined so that if executed on older cpus, they would behave as
nops.  This allows us to emit them on older cpus and they'd just be
ignored, but if run on a Power10, then the binary would be ROP protected.

Hash instructions use negative offsets so the default position
of ROP pointer is FRAME_ROP_SAVE from caller's SP.

Modified FRAME_MIN_SIZE_PARM to 112 for ELFv2 to reserve
additional 16 bytes for ROP save slot and padding.
