2bf81922f7 internal: more reasonable grammar for blocks
Consider these expples

        { 92 }
  async { 92 }
    'a: { 92 }
   #[a] { 92 }

Previously the tree for them were

  BLOCK_EXPR
    { ... }

  EFFECT_EXPR
    async
    BLOCK_EXPR
      { ... }

  EFFECT_EXPR
    'a:
    BLOCK_EXPR
      { ... }

  BLOCK_EXPR
    #[a]
    { ... }

As you see, it gets progressively worse :) The last two items are
especially odd. The last one even violates the balanced curleys
invariant we have (#10357) The new approach is to say that the stuff in
`{}` is stmt_list, and the block is stmt_list + optional modifiers

  BLOCK_EXPR
    STMT_LIST
      { ... }

  BLOCK_EXPR
    async
    STMT_LIST
      { ... }

  BLOCK_EXPR
    'a:
    STMT_LIST
      { ... }

  BLOCK_EXPR
    #[a]
    STMT_LIST
      { ... }

5c9f31d4c2 internal: move diagnostics to hir
The idea here is to eventually get rid of `dyn Diagnostic` and
`DiagnosticSink` infrastructure altogether, and just have a `enum
hir::Diagnostic` instead.

The problem with `dyn Diagnostic` is that it is defined in the lowest
level of the stack (hir_expand), but is used by the highest level (ide).

As a first step, we free hir_expand and hir_def from `dyn Diagnostic`
and kick the can up to `hir_ty`, as an intermediate state. The plan is
then to move DiagnosticSink similarly to the hir crate, and, as final
third step, remove its usage from the ide.

One currently unsolved problem is testing. You can notice that the test
which checks precise diagnostic ranges, unresolved_import_in_use_tree,
was moved to the ide layer. Logically, only IDE should have the infra to
render a specific range.

At the same time, the range is determined with the data produced in
hir_def and hir crates, so this layering is rather unfortunate. Working
on hir_def shouldn't require compiling `ide` for testing.

fb1f544e24 Use Box'es to reduce size of hir_def::expr::Expr from 128 to 72 bytes (on 64bit systems)
Rationale: only a minority of variants used almost half the size.
By keeping large members (especially in Option) behind a box
the memory cost is only payed when the large variants are needed.

This reduces the size Vec<Expr> needs to allocate.

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.
