Remove some superfluous type parameters from layout.rs.
...
Specifically remove V, which can always be VariantIdx, and F, which can
always be Layout.

Remove double spaces after dots in comments
Most of the comments do not have double spaces, so I assume these are typos.

Add 0..=isize::MAX range metadata to size loads from vtables
This is the (much belated) size counterpart to #91569 .
Inspired by https://rust-lang.zulipchat.com/#narrow/stream/187780-t-compiler.2Fwg-llvm/topic/Range.20metadata.20for.20.60size_of_val.60.20and.20other.20isize.3A.3AMAX.20limits . This could help optimize layout computations based on the size of a dyn trait. Though, admittedly, adding this to vtables wouldn't be as beneficial as adding it to slice len, which is used much more often.
Miri detects this UB already: b7cc99142a/compiler/rustc_const_eval/src/interpret/traits.rs (L119-L121)9db224fc90/compiler/rustc_abi/src/lib.rs (L312-L331)

...
Add StableOrd trait as proposed in MCP 533.
The `StableOrd` trait can be used to mark types as having a stable sort order across compilation sessions. Collections that sort their items in a stable way can safely implement HashStable by hashing items in sort order.
See https://github.com/rust-lang/compiler-team/issues/533 for more information.

Remove useless borrows and derefs
They are nothing more than noise.
