Mingming Liu 9747bb182f [CodeGen][StaticDataSplitter]Support constant pool partitioning (#129781) ...

This is a follow-up patch of
https://github.com/llvm/llvm-project/pull/125756

In this PR, static-data-splitter pass produces the aggregated profile
counts of constants for constant pools in a global state
(`StateDataProfileInfo`), and asm printer consumes the profile counts to
produce `.hot` or `.unlikely` prefixes.

This implementation covers both x86 and aarch64 asm printer.
