bb27b05104 Separate RemoveFalseEdges from SimplifyBranches 
Otherwise dataflow state will propagate along false edges and cause
things to be marked as maybe init unnecessarily. These should be
separate, since `SimplifyBranches` also makes `if true {} else {}` into
a `goto`, which means we wouldn't lint anything in the `else` block.

Rollup merge of #90071 - cjgillot:no-blocks, r=oli-obk 
Remove hir::map::blocks and use FnKind instead

The principal tool is `FnLikeNode`, which is not often used and can be easily implemented using `rustc_hir::intravisit::FnKind`.

1418df5888 Adopt let_else across the compiler 
This performs a substitution of code following the pattern:

let <id> = if let <pat> = ... { identity } else { ... : ! };

To simplify it to:

let <pat> = ... { identity } else { ... : ! };

By adopting the let_else feature.

Rollup merge of #88709 - BoxyUwU:thir-abstract-const, r=lcnr 
generic_const_exprs: use thir for abstract consts instead of mir

Changes `AbstractConst` building to use `thir` instead of `mir` so that there's less chance of consts unifying when they shouldn't because lowering to mir dropped information (see `abstract-consts-as-cast-5.rs` test)
