Rollup merge of #102675 - ouz-a:mir-technical-debt, r=oli-obk 
Remove `mir::CastKind::Misc`

As discussed in #97649 `mir::CastKind::Misc` is not clear, this PR addresses that by creating a new enum variant for every valid cast.

Rollup merge of #99027 - tmiasko:basic-blocks, r=oli-obk 
Replace `Body::basic_blocks()` with field access

Since the refactoring in #98930, it is possible to borrow the basic blocks
independently from other parts of MIR by accessing the `basic_blocks` field
directly.

Replace unnecessary `Body::basic_blocks()` method with a direct field access,
which has an additional benefit of borrowing the basic blocks only.

31d892a942 Fix liveness analysis for yield terminators 
A resume place is evaluated and assigned to only after a yield
terminator resumes. Ensure that locals used when evaluating the
resume place are live across the yield.
