This ICEs in MIR currently, which I think is to be expected since none of the MIR plumbing is set up. I added a test which confirms that the shim is being used for reifying a track_caller function.
Remove query-related macros
The query system has a few macros that only have one or two call sites, and I find they hurt readability. This PR removes them.

Remove loaded_from_cache map from DepGraph
It's now unused, even with -Zquery-dep-graph
From https://github.com/rust-lang/rust/pull/63756/files#r316039379 -- it'll simplify that PR to get this landed separately so we can just remove some of the code that it touches.

fix bug in folding for constants
These was a bug in the folding for constants that caused it to overlook bound regions. This branch includes some other little things that I did while trying to track the bug down.

Optimize integral pattern matching
Various improvements to integral pattern matching. Together they reduce instruction counts for `unicode_normalization-check-clean` by about 16%.
r? @Mark-Simulacrum
The `if let Some(val) = value.try_eval_bits(...)` branch in `from_const()` is
very hot for the `unicode_normalization` benchmark.
This commit introduces a special-case alternative for scalars that avoids
`try_eval_bits()` and all the functions it calls (`Const::eval()`,
`ConstValue::try_to_bits()`, `ConstValue::try_to_scalar()`, and
`Scalar::to_bits()`), instead extracting the result immediately.
The type and value checking done by `Scalar::to_bits()` is replicated by moving
it into a new function `Scalar::check_raw()` and using that new function in the
special case.
PR #64673 introduced some special-case handling of scalar types in
`Const::try_eval_bits()`. This handling is now moved out of that function into
the new `IntRange::integral_size_and_signed_bias` function.
This commit reduces the instruction count for
`unicode_normalization-check-clean` by about 10%.
SelfProfiler API refactoring and part one of event review
This PR refactors the `SelfProfiler` a little bit so that most profiling methods are RAII-based. The codegen backend code already had something similar, this refactoring pulls this functionality up into `SelfProfiler` itself, for general use.
The second commit of this PR is a review and update of the existing events we are already recording. Names have been made more consistent. CGU names have been removed from event names. They will be added back in when function parameter recording is implemented.
There is still some work to be done for adding new events, especially around trait resolution and the incremental system.

async/await: improve not-send errors
cc #64130.

note: future does not implement `std::marker::Send` because this value is used across an await
