perf annotate: Update parameters for reg extract functions to use raw instruction on powerpc

Browse Source 
Use the raw instruction code and macros to identify memory instructions,
extract register fields and also offset.

The implementation addresses the D-form, X-form, DS-form instructions.

Adds "mem_ref" field to check whether source/target has memory
reference.

Add function "get_powerpc_regs" which will set these fields: reg1, reg2,
offset depending of where it is source or target ops.

Update "parse" callback for "struct ins_ops" to also pass "struct
disasm_line" as argument. This is needed in parse functions where opcode
is used to determine whether to set multi_regs and other fields
