Cleanup macro matching recovery
The retry has been implemented already in #104335. Also removes a `HACK` comment that's not really needed anymore because the "don't recover during macro matching" isn't really a hack but correct behavior.

Fix substraction with overflow in `wrong_number_of_generic_args.rs`
Fixes #104287
This issue happens in the `suggest_moving_args_from_assoc_fn_to_trait_for_qualified_path` function, which seems to run before the error checking facilities can catch an invalid use of generic arguments. Thus we get a subtraction with overflow because the code implicitly assumes that the source program makes sense (or is this assumption not true even if the program is correct?).

`VecDeque::resize` should re-use the buffer in the passed-in element
Today it always copies it for *every* appended element, but one of those clones is avoidable.
This adds `iter::repeat_n` (https://github.com/rust-lang/rust/issues/104434) as the primitive needed to do this. If this PR is acceptable, I'll also use this in `Vec` rather than its custom `ExtendElement` type & infrastructure that is harder to share between multiple different containers:

Auto merge of #104470 - ehuss:cdb-dupe-last-command, r=jyn514
Don't duplicate last cdb debuginfo test command
cdb scripts interpret a blank line to mean "repeat the last command", similar to what happens when running the debugger from a console. The code for compiletest that constructs the debugger script was inserting a blank line between the last command and the "quit" command. This caused the last command to be executed twice. This can cause some confusion since the `-check` lines are expecting the output in a certain order. But printing the last command twice causes that order-assumption to fail, and that can cause confusion.
This fixes it by removing the blank line.
AFAICT, gdb and lldb scripts don't have the same behavior with blank lines (and the gdb code doesn't add any blank lines anyways).

Partial support for running UI tests with `download-rustc`
Right now trying to run UI tests with `download-rustc` results in a bunch of test failures, requiring someone who wants to only work on tests to also build the full compiler. This PR **partially** addresses the problem by solving a lot of the errors (but not all).
* This installs the `rust-src` component on CI toolchains, since the test output depends on whether the standard library source code is installed; We can't just symlink the current source because the `rustc-dev` component already includes the compiler sources, but not the library sources, and mixing things is worse IMO.
* This ensures the `$SRC_DIR` normalization done by compiletest correctly handles the source code added above.
* This unconditionally sets `remap-prefix` to the prefix used in the downloaded toolchain, to ensure compiletest normalizes it.

Diagnostics `icu4x` based list formatting.
This adds a new kind of `DiagnosticArg` and add the ability to convert it to a `FluentValue::Custom`. When emitting fluent output, it makes use of `ListFormatter` from `icu4x` project to convert it to localized version of list following the fluent locale, as a kind of eager translation.
Tested locally with locales like `en`, `ja`, etc, and they work fine. <del>Though neither `zh-CN` nor `zh-Hans` works correctly, it seems they fallback to `und` locale somehow, emitting only comma-based list.

Rollup merge of #103378 - nagisa:fix-infinite-offset, r=scottmcm
Fix mod_inv termination for the last iteration
On usize=u64 platforms, the 4th iteration would overflow the `mod_gate` back to 0. Similarly for usize=u32 platforms, the 3rd iteration would overflow much the same way.
I tested various approaches to resolving this, including approaches with `saturating_mul` and `widening_mul` to a double usize. Turns out LLVM likes `mul_with_overflow` the best. In fact now, that LLVM can see the iteration count is limited, it will happily unroll the loop into a nice linear sequence.
You will also notice that the code around the loop got simplified somewhat. Now that LLVM is handling the loop nicely, there isn’t any more reasons to manually unroll the first iteration out of the loop (though looking at the code today I’m not sure all that complexity was necessary in the first place).

`_` might confuse people into believing that the type isn't known,
while `...` is not used anywhere else for types and is not valid
