If the client support our server status notification there is no need to show the pop up for workspace fetching failures since that's already going to be shown in the status.

fix: show diagnostic for } token followed by else in let else statement
fix#14221
My thinking is to check if the `expr` after `=` is block like when parse `let ... lese` , and if so, emit error.
MIR episode 2
This PR adds:
1. `need-mut` and `unused-mut` diagnostics
2. `View mir` command which shows MIR for the body under cursor, useful for debugging
3. MIR lowering for or-patterns and for-loops
internal: Mark unresolved field, unresolved method and expected function diagnostics experimental
Our type checking is still not good enough for us to have these diagnostics be enabled by default it seems so let's mark them as experimental for now.
internal: Re-use the resolver in `InferenceContext` instead of rebuilding it whenever needed
This reduced inference time on my local build by roughly ~1 sec (out of like 60)
internal: Handle fields called as method calls as the fields they resolve to
Confusing PR title tbf but this makes it so `bar` in `foo.bar()` resolves to the field if it exists and no method with the same name exists. Improves UX slightly when incorrectly calling a field.
generate correct completion edits for missing macro arguments
Fixes#14246
rust-analyzer used the token at the cursor after macro expansion to decide whether to replace the token at the cursor before macro expansion. In most cases these two are the same but in some cases these can mismatch which can lead to incorrect replacements.
For example if an ident/expr macro argument is missing rust-analyzer generates a "missing" identifier as a placeholder, there is only a brace at the cursor. Therefore, rust-analyzer will incorrectly replace the macro brace with the completion in that case leading to #14246.
Using the expanded token type was intentional. However, this doesn't seem to ever be desirable (this is supported by the fact that there were no tests that relied on this behavior) since the type of edit to perform should always be determined by the token it's actually applied to. Therefore this PR simply switches the relevant match to use the unexpanded token instead
