e3f2edc75b Rename Abort terminator to Terminate 
Unify terminology used in unwind action and terminator, and reflect
the fact that a nounwind panic is triggered instead of an immediate
abort is triggered for this terminator.

a2ee7592d6 Use &IndexSlice instead of &IndexVec where possible 
All the same reasons as for `[T]`: more general, less pointer chasing, and `&mut IndexSlice` emphasizes that it doesn't change *length*.

e489971902 Fix def-use dominance check 
A definition does not dominate a use in the same statement. For example
in MIR generated for compound assignment x += a (when overflow checks
are disabled).

fa41852c7a Use reverse postorder in non_ssa_locals 
The reverse postorder, unlike preorder, is now cached inside the MIR
body. Code generation uses reverse postorder anyway, so it might be
a small perf improvement to use it here as well.

40c9aaee13 Do not emit alloca for ZST locals with multiple assignments 
When rebuilding the standard library with `-Zbuild-std` this reduces the
number of locals that require an allocation from 62315 to 61767.

624c693508 Remove check for projections in a branch without any 
The else branch is taken when projection slice is empty so everything
except for the call to the `visit_local` is a dead code.

76695c41da Remove special handling of box_free from LocalAnalyzer 
The special casing of `box_free` predates the use of dominators in
analyzer. It is no longer necessary now that analyzer verifies that
the first assignment dominates all uses.

e655fb6221 Auto merge of #82936 - oli-obk:valtree, r=RalfJung,lcnr,matthewjasper 
Implement (but don't use) valtree and refactor in preparation of use

This PR does not cause any functional change. It refactors various things that are needed to make valtrees possible. This refactoring got big enough that I decided I'd want it reviewed as a PR instead of trying to make one huge PR with all the changes.

cc `@rust-lang/wg-const-eval` on the following commits:

* 2027184 implement valtree
* eeecea9 fallible Scalar -> ScalarInt
* 042f663 ScalarInt convenience methods

cc `@eddyb` on ef04a6d

cc `@rust-lang/wg-mir-opt` for cf1700c (`mir::Constant` can now represent either a `ConstValue` or a `ty::Const`, and it is totally possible to have two different representations for the same value)
