Unrolled build for rust-lang#132347

Rollup merge of rust-lang#132347 - nnethercote:rm-ValueAnalysisWrapper, r=cjgillot

Remove `ValueAnalysis` and `ValueAnalysisWrapper`.

They represent a lot of abstraction and indirection, but they're only used for `ConstAnalysis`, and apparently won't be used for any other analyses in the future. This commit inlines and removes them, which makes `ConstAnalysis` easier to read and understand.

r? `@cjgillot`
