cargo fails to build on Windows with nightly

[wesleywiser]

Building cargo on Windows (-msvc toolchain) causes an ICE:

PS D:\code\cargo> cargo +nightly build      
   Compiling cargo v0.58.0 (D:\code\cargo)
thread 'rustc' panicked at 'assertion failed: !value.has_escaping_bound_vars()', /rustc/1f12ac87296ac61ec002e0243e7ad5a50364da35\compiler\rustc_middle\src\ty\sty.rs:974:9
error: internal compiler error: unexpected panic

note: the compiler unexpectedly panicked. this is a bug.

note: we would appreciate a bug report: https://github.com/rust-lang/rust/issues/new?labels=C-bug%2C+I-ICE%2C+T-compiler&template=ice.md

note: rustc 1.58.0-nightly (1f12ac872 2021-10-17) running on x86_64-pc-windows-msvc

note: compiler flags: -C embed-bitcode=no -C debuginfo=2 -C incremental --crate-type lib

note: some of the compiler flags provided by cargo are hidden

[michaelwoerister]

I'll look into it.

[wesleywiser]

Since #89597 landed in 1.57, labeling as stable-to-beta regression.

[wesleywiser]

Re-opening to track the beta backport.
