Rollup merge of #139819 - Kobzol:rust-cache, r=marcoieni 
Use `rust-cache` to speed-up `citool` compilation

Alternative to https://github.com/rust-lang/rust/pull/139678.

Rollup merge of #139818 - compiler-errors:normalize-tails, r=oli-obk 
Normalize ADT field in `find_tails_for_unsizing`

See the comment inline and in the test.

TL;DR is that we're getting getting a type from a `type_of` query and then matching on it structurally in codegen, so we're obligated to normalize it. The fact that this wasn't triggered earlier is that all of the types that have `CoerceUnsized` implementations never encounter aliases when peeling the ADT down to their base reference/ptr type.

**NOTE**: I also renamed some things and reorganized the function a bit.

Fixes #139812
Fixes #74451, which I didn't think was interesting enough to add another test.

043c5ff982 Add warning comment to Take::get_ref and Chain::get_ref 
The methods `Take::get_mut` and `Chain::get_mut` include comments
warning about modifying the I/O state of the underlying reader. However,
many readers (e.g. `File`) allow I/O using a shared reference (e.g.
`&File`). So, add the same caveat to the `get_ref` methods.

Reject test executables when not supported by target

Currently, compiling tests for SOLID produces an ICE, because SOLID does not support executables.

Improve diagnostic for E0178 (bad + in type) 
Namely, use a more sensical primary span.
Don't pretty-print AST nodes for the diagnostic message. Why:
* It's lossy (e.g., it doesn't replicate trailing `+`s in trait objects.
* It's prone to leak error nodes (printed as `(/*ERROR*/)`) since
  the LHS can easily represent recovered code (e.g., `fn(i32?) + T`).

c12b4aade0 Use a dummy ident for a lint_if_path_starts_with_module call. 
This is pretty weird code. As the `HACK` comment indicates, we push the
empty ident here only to make the path longer, so certain checks to
occur within `lint_if_path_starts_with_module`. `dummy` is a better
choice because it explicitly communicates that the actual value doesn't
matter.

f3847f0639 Remove some "name isn't empty" assertions. 
These were low value even before #137978 resulted in empty names being
used much less. (Why check for non-emptiness in these three places?
There are thousands of places in the compiler you could check.)

This change maps the EOPNOTSUPP errno value (95) to std::io::ErrorKind::Unsupported in the decode_error_kind function for Unix platforms. Previously, it was incorrectly mapped to ErrorKind::Uncategorized.
