perf annotate: Update instruction tracking for powerpc

Add instruction tracking function "update_insn_state_powerpc" for
powerpc. Example sequence in powerpc:

  ld      r10,264(r3)
  mr      r31,r3
  <<after some sequence>
  ld      r9,312(r31)

Consider ithe sample is pointing to: "ld r9,312(r31)".

Here the memory reference is hit at "312(r31)" where 312 is the offset
and r31 is the source register.

Previous instruction sequence shows that register state of r3 is moved
to r31.

So to identify the data type for r31 access, the previous instruction
("mr") needs to be tracked and the state type entry has to be updated.

Current instruction tracking support in perf tools infrastructure is
specific to x86. Patch adds this support for powerpc as well.
