Utilize a smart hash for 'llvm-finished-building' to enable
recompilation of LLVM with each change in the git sources.

Each change generates a unique hash value in 'llvm-finished-building',
which ensures LLVM compilations only triggered with further changes.

Recompile LLVM when it changes in the git sources

Utilize a smart hash for 'llvm-finished-building' to enable recompilation of LLVM with each change in the git sources.

Each change generates a unique hash value in 'llvm-finished-building', which ensures LLVM compilations only triggered with further changes.

Resolves rust-lang#111893

…wu, r=compiler-errors

intercrate ambiguity causes: ignore candidates which don't apply

r? `@compiler-errors`
Add common trait for crate definitions

In stable mir, we specialize DefId, however some functionality is the same for every definition, such as def paths, and getting their crate. Use a trait to implement those.
memcpy assumptions: update GCC link

GCC now has this documented on an official website, not just in the bugtracker.
EvalCtxt::commit_if_ok don't inherit nested goals

we use it to check whether an alias is rigid, so we want to avoid considering an alias rigid simply because the inference constraints from normalizing it caused another nested goal fail

r? `@compiler-errors`
…, r=compiler-errors

Add `Span` to `TraitBoundModifier`

This improves diagnostics for the message "`~const` is not allowed here", and also fixes the span that we use when desugaring `~const Tr` into `Tr<host>` in effects desugaring.

Remove a hack for effects

Fallback was implemented in rust-lang#115727, which addresses the inference errors mentioned in the comments.
