Go back to Some instead of transmuting to it.
...
This adds a few more statements to `next`, but optimizes better in the loops (saving 2 blocks in `forward_loop`, for example)

Save another BB by using SubUnchecked instead of a call to arith_offset
...
Probably reasonable anyway since it more obviously drops provenance.

[mir-opt] GVN some more transmute cases
...
We already did `Transmute`-then-`PtrToPtr`; this adds the nearly-identical `PtrToPtr`-then-`Transmute`.
It also adds `transmute(Foo(x))` → `transmute(x)`, when `Foo` is a single-field transparent type. That's useful for things like `NonNull { pointer: p }.as_ptr()`.
Found these as I was looking at MCP807-related changes.

Ban ArrayToPointer and MutToConstPointer from runtime MIR
...
Apparently MIR borrowck cares about at least one of these for checking variance.
In runtime MIR, though, there's no need for them as `PtrToPtr` does the same thing.
(Banning them simplifies passes like GVN that no longer need to handle multiple cast possibilities.)

Rename adjustment::PointerCast and variants using it to PointerCoercion
...
It makes it sound like the `ExprKind` and `Rvalue` are supposed to represent all pointer related
casts, when in reality their just used to share a some enum variants. Make it clear there these
are only coercion to make it clear why only some pointer related "casts" are in the enum.
