[CodeGen] Introduce Static Data Splitter pass (#122183)
https://discourse.llvm.org/t/rfc-profile-guided-static-data-partitioning/83744
proposes to partition static data sections.
This patch introduces a codegen pass. This patch produces jump table
hotness in the in-memory states (machine jump table info and entries).
Target-lowering and asm-printer consume the states and produce `.hot`
section suffix. The follow up PR
https://github.com/llvm/llvm-project/pull/122215 implements such
changes.
