[DO NOT MERGE] bootstrap with -Znext-solver=globally

[lcnr]

A revival of #124812.

Current status:

./x.py b --stage 2 passes 🎉

try builds succeed 🎉 🎉 🎉

first perf run 👻

in-flight changes

• alias-relate: add fast reject optimization #124852, unsure whether I actually want to land this PR for now
• support revealing uses of opaques in closures #139587
• https://github.com/lcnr/rust/tree/opaque-type-method-call

I also pushed:

• Deeply normalize when computing implied outlives bounds #133517
• Structurally resolve before checking ! in HIR typeck #133518
• Check xform_ret_ty for WF in the new solver to improve method winnowing #133519
• Structurally resolve before applying projection in borrowck #133520
• Structurally resolve before matching on type of projection #133521
• Cache in DeepRejectCtxt #133524

I think this is sufficient to make the compiler build, or at least ./x.py build --stage=2 completes successfully on my local branch.

I was reducing the new failure but you've already fixed it ^^

[lcnr]

with wg-grammer/gll now also compiling, I am interested in whether there are any other issues in the wild. Let's start with just checking the top 100 crates
