There might be more type params than args to a method call, which leads to an
index out of bounds panic.

These are already slices, no need to slice them again

Use id-based thread parking on SOLID

By using the [`slp_tsk`/`wup_tsk`](https://cs.uwaterloo.ca/~brecht/courses/702/Possible-Readings/embedded/uITRON-4.0-specification.pdf) system functions instead of an event-flag structure, `Parker` becomes cheaper to construct and SOLID can share the implementation used by NetBSD and SGX.

Fix index out of bounds ICE in `point_at_expr_source_of_inferred_type`

There might be more type params than args to a method call, which leads to an index out of bounds panic.
I'm not familiar with this code at all, so unsure whether this is the right fix, but at least this patch fixes rust-lang#108042 for me (I hit the same issue with similar code)

Constify `RangeBounds`, `RangeX::contains` and `RangeX::is_empty` (where applicable).

don't clone types that are copy

simplify some refs

be nice and don't slice

These are already slices, no need to slice them again
