Subject: [PATCH 1/3] tools/perf/arch/powerpc: Add load/store in powerpc annotate instructions for data type profling

From: Athira Rajeev <[email-masked]>
Date: Sat, 9 Mar 2024 12:55:11 +0530

Add powerpc instruction nmemonic table to associate load/store
instructions with move_ops. mov_ops is used to identify mem_type
to associate instruction with data type and offset. Also initialize
and allocate arch specific fields for nr_instructions, instructions and
nr_instructions_allocate.
