This resolves issues where the cross-build of LLVM fails because it tries to
link to the host's system libraries instead of the target's system libraries.

In this instance, we can just pass a &str slice
and save an allocation.

.into() guarantees safety of the conversion.
Furthermore, the minimum value of all uints is known to be 0.

Unify const-checking structured errors for `&mut` and `&raw mut`

Resolves rust-lang#77414 as well as a FIXME.

Support signed integers and `char` in v0 mangling

Likely we want more tests, to check the output is correct too: however, I wasn't sure what kind of test we needed, so I just added one similar to that added in rust-lang#77452 for now.

Mark inout asm! operands as used in liveness pass

Variables used in `inout` operands in inline assembly (that is, they're used as both input and output to some arbitrary assembly instruction) are being marked as read and written, but are not marked as being used in the RWU table during the liveness pass. This can result in such expressions triggering an unused variable lint warning. This is incorrect behavior- reads without uses are currently only used for compound assignments. We conservatively assume that an `inout` operand is being read and used in the context of the assembly instruction.

Haiku: explicitly set CMAKE_SYSTEM_NAME when cross-compiling

This resolves issues where the cross-build of LLVM fails because it tries to
link to the host's system libraries instead of the target's system libraries.

Greatly improve display for small mobile devices screens

Fixes rust-lang#78014.

The biggest change being the "search bar". Instead of having everything on one line, I decided to move the search input on its own:

Another change is that now, we "break words" in the listing so that they don't grow too big:
