8201: Fix recursive macro statements expansion r=edwin0cheng a=edwin0cheng

This PR attempts to properly handle macro statement expansion by implementing the following:

1.  Merge macro expanded statements to parent scope statements.
2.  Add a new hir `Expr::MacroStmts` for handle tail expression infer.

PS : The scope of macro expanded statements are so strange that it took more time than I thought to understand and implement it :(

Fixes  #8171

8063: couple clippy::complexity fixes r=matklad a=matthiaskrgr

avoid redundant `.into()` calls to convert T into identical T (`let x: String = String::from("hello").into();`)
use `if let Some(x)` instead of `.is_some()` + `.unwrap()`
don't clone Copy types
remove redundant wrapped ?s:  `Some(Some(3)?)` can just be `Some(3)`
use `.map(|x| y)` instead of `and_then(|x| Some(y)` on `Option`s

Merge #8048 
8048: Fix missing unresolved macro diagnostic in function body r=edwin0cheng a=brandondong

This was an issue I found while working on https://github.com/rust-analyzer/rust-analyzer/pull/7970.

**Reproduction:**
1. Call a non-existent macro in a function body.
```
fn main() {
  foo!();
}
```
2. No diagnostics are raised. An unresolved-macro-call diagnostic is expected.
3. If the macro call is instead outside of the function body, this works as expected.

I believe this worked previously and regressed in https://github.com/rust-analyzer/rust-analyzer/pull/7805.

**Behavior prior to https://github.com/rust-analyzer/rust-analyzer/pull/7805:**
- The unresolved-macro-call diagnostic did not exist. Instead, a macro-error diagnostic would be raised with the text "could not resolve macro [path]".
- This was implemented by adding an error to the error sink (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8L657).
- The error was propagated through 1a82af3527/crates/hir_def/src/body.rs (L123) eventually reaching 1a82af3527/crates/hir_def/src/body/lower.rs (L569).

**Behavior after:**
- Instead of writing to the error sink, an UnresolvedMacro error is now returned (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8R631).
- The parent caller throws away the error as its function signature is `Option<MacroCallId>` (https://github.com/rust-analyzer/rust-analyzer/pull/7805/files#diff-50a326c5ae465bd9b31ee4310186380aa06e4fa1f6b41dbc0aed5bcc656a3cb8R604).
- We instead now reach the warn condition (1a82af3527/crates/hir_def/src/body.rs (L124)) and no diagnostics are created in 1a82af3527/crates/hir_def/src/body/lower.rs (L575).

**Fix:**
- Make sure to propagate the UnresolvedMacro error. Report the error using the new unresolved-macro-call diagnostic.

Merge #7994 
7994: Speed up mbe matching in heavy recursive cases r=edwin0cheng a=edwin0cheng

In some cases (e.g.  #4186), mbe matching is very slow due to a lot of copy and allocation for bindings, this PR try to solve this problem by introduce a semi "link-list" approach for bindings building.

I used this [test case](https://github.com/weiznich/minimal_example_for_rust_81262) (for `features(32-column-tables)`) to run following command to benchmark:
```
time rust-analyzer analysis-stats  --load-output-dirs ./ 
```

Before this PR : 2 mins
After this PR: 3 seconds.

However, for 64-column-tables cases, we still need 4 mins to complete. 

I will try to investigate in the following weeks.
