adds a column number to `dbg!()`
this would be very nice to have for a few reasons:
1. the rfc, when deciding not to add column numbers to macro, failed to acknowledge any potential ambiguous cases -- such as the one provided in #114910 -- which do exist
2. would be able to consistently and easily jump directly to the `dbg!()` regardless of the sutation
3. takes up, at a maximum, 3 characters of _horizontal_ screen space
fixes#114910
The compiler-builtins for RISC-V are missing some key functions, such as
__bswapsi2 [1].
We can't just pull in the LLVM compiler-rt builtins as the rust-lang/rust
distribution container doesn't have a C compiler [2].
This patch adds RISC-V C compilers to the CI Dockerfile as the first
step towards enabling LLVM compiler-rt builtins for RISC-V Rust.

Remove unnecessary constness from ProjectionCandidate
Constness in an item bound will be represented by an effect param, so no need to record constness here.

fix: Overlapping spans in delimited meta-vars
Closes#118786
Delimited meta-vars inside of MBE's spans were set to have the same opening and closing position resulting in an ICE when debug assertions were enabled and an error was present in the templated code.
This ensures that the spans do not overlap, whilst still having the spans point at the usage of the meta-var inside the macro definition.
It includes a regression test.

More expressions correctly are marked to end with curly braces
Fixes#118859, and replaces the mentioned match statement with an exhaustive list, so that this code doesn't get overlooked in the future
skip rpit constraint checker if borrowck return type error
Fixes#117794Fixes#117886Fixes#119025
Prior to change #117418, the value of `concrete_opaque_types` for `mir_borrock(T:🅰️:opaque)` was `None`. However, due to modifications in `body.local_decls`, the return value had been changed.
The changed of `body.local_decls` has let to the addition of `ty:Error` to `infcx.opaque_type_storage.opaque_types` during `TypeChecker::equate_inputs_and_outputs`. This is due to it utilizing the output of a function signature that was appended during `construct_error`(which previously only appended a `ty::Error`) and then execute `TypeChecker::Related_types`.
Therefore, in this PR, I've implemented a condition to bypass the rpit check when an error is encountered.

remove `hex` dependency in bootstrap
First commit removes the `hex` dependency, as we can achieve the same output with the added function, which is very small and simple.
Second commit creates a test module for the helpers util and adds unit tests for multiple helper functions, including `hex_encode`.
Visit the AllocIds and BorTags in borrow state FrameExtra
Fixes https://github.com/rust-lang/miri/issues/3228
I said
> The obvious way would be to visit the AllocIds in borrow_tracker::FrameExtra in the GC.
Since I have had no new ideas, that's what this does.
rustdoc-search: remove parallel searchWords array
This might have made sense if the algorithm could use `searchWords` to skip having to look at `searchIndex`, but since it always does a substring check on both the stock word and the normalizedName, it doesn't seem to help performance anyway.
