Stop suggesting a float truncation that is not shorter
Fixes#7721.
Previously Clippy would say that a number has excessive precision even if it has the minimum possible precision for the floating point value that it corresponds to.
changelog: Fix [`excessive_precision`] being triggered on floats that are already written in shortest form
Turns out, this has some really bad perf implications in large types (issue #88862). While we technically can handle them fine, it doesn't change test output either way. For now, revert with an added benchmark. Future attempts to change this back will have to consider perf.
* Make define_global() return a RValue directly
* Return LValue in functions declaring a global variable
* Remove useless cast
* Fix bytes_in_context to use an array rvalue
* Remove global_names which is unused
* Make const_struct create a constant struct
* Correctly initialize global in static_addr_of_mut
* Fix global variable initialization
* Remove workaround for ARGV
Remove most box syntax uses from the testsuite except for src/test/ui/issues
Removes most box syntax uses from the testsuite outside of the src/test/ui/issues directory. The goal was to only change tests where box syntax is an implementation detail instead of the actual feature being tested. So some tests were left out, like the regression test for #87935, or tests where the obtained error message changed significantly.
Mostly this replaces box syntax with `Box::new`, but there are some minor drive by improvements, like formatting improvements or `assert_eq` instead of `assert!( == )`.
Prior PR that removed box syntax from the compiler and tools: #87781
Support incremental in compiletest for non-incremental modes.
This adds first-class support for using incremental builds in non-incremental-mode tests. These tests previously manually passed `-C incremental=tmp/foo` which resulted in reusing the same tmp folder between runs. This means that these tests could fail whenever the on-disk incremental format changed (such as when updating one's local source tree). This changes it so that these tests can pass a `// incremental-build` header which instructs compiletest to create a set aside a dedicated incremental directory which will be cleared before the test starts to ensure it has a clean slate.
Validate builtin attributes for macro args.
This adds some validation for `path`, `crate_type`, and `recursion_limit` attributes so that they will now return an error if you attempt to pass a macro into them (such as `#[path = foo!()]`). Previously, the attribute would be completely ignored. These attributes are special because their values need to be known before/during expansion.

rustdoc: Cleanup `clean` part 2
Split out from #88379. This contains the following commits from that PR:
- Remove `Type::ResolvedPath.is_generic`
- Rename `is_generic()` to `is_assoc_ty()`
r? `@jyn514`
Now `Fields` is just a `Vec` of patterns, with some extra info on the
side to reconstruct patterns when needed. This emphasizes that this
extra info is not central to the algorithm.
