7a4fdcbbc5 Remove unnecessary fields from EnumNonMatchingCollapsed. 
The `&[ast::Variant]` field isn't used.

The `Vec<Ident>` field is only used for its length, but that's always
the same as the length of the `&[Ident]` and so isn't necessary.

72a1621061 Use split_{first,last} in cs_fold1. 
It makes the code a little nicer to read.

b33c6e1bd8 Do not error on the param_env during inlining. 
This created unexpected diagnostics while compiling alga:
    cannot satisfy `<Self as Module>::Ring == _`

Turns out that we don't need this diagnostic as we disable inlining when
it would trigger an ICE.

5999f34ff6 Don't assert polymorphization has taken effect in const eval 
Const eval no longer runs MIR optimizations so unless this is getting
run as part of a MIR optimization like const-prop, there can be unused
type parameters even if polymorphization is enabled.

interpret: add From<&MplaceTy> for PlaceTy

We have a similar instance for `&MPlaceTy` to `OpTy`. Also add the same for `&mut`.

This avoids having to write `&(*place).into()`, which we have a few times here and at least twice in Miri (and it comes up again in my current patch).

r? ```@oli-obk```

llvm-wrapper: adapt for LLVMConstExtractValue removal

`LLVMConstExtractValue` was removed recently from LLVM: 5548e807b5.

This adapts llvm-wrapper to use the new alternative where available, following https://rust-lang.zulipchat.com/#narrow/stream/187780-t-compiler.2Fwg-llvm/topic/LLVMConstExtractValue.20removal.

7fda86249f promote placeholder bounds to 'static obligations 
In NLL, when we are promoting a bound out from a closure,
if we have a requirement that `T: 'a` where `'a` is in a
higher universe, we were previously ignoring that, which is
totally wrong. We should be promoting those constraints to `'static`,
since universes are not expressible across closure boundaries.

7425fb293f Auto merge of #98377 - davidv1992:add-lifetimes-to-argument-temporaries, r=oli-obk 
Added llvm lifetime annotations to function call argument temporaries.

The goal of this change is to ensure that llvm will do stack slot
optimization on these temporaries. This ensures that in code like:
```rust
const A: [u8; 1024] = [0; 1024];

fn copy_const() {
    f(A);
    f(A);
}
```
we only use 1024 bytes of stack space, instead of 2048 bytes.

I am new to developing for the rust compiler, and as such not entirely sure, but I believe this should be sufficient to close #98156.

Also, this does not contain a test case to ensure this keeps working, primarily because I am not sure how to go about testing this. I would love some suggestions as to how that could be approached.
