…ponding HIR types

Update rustc_pattern_analysis

This should fix rust-lang/rust-analyzer#16656 but I can't check because we don't have a reproducer.

internal: sync from downstream

fix: Add basic support for Native Debug

Native Debug doesn't work very well and passing command-line arguments is nasty (rust-lang/rust-analyzer#9815), but I guess it's a start.

Closes rust-lang#9815

fix: autocomplete constants inside format strings

Hi! This PR adds autocompletion for constants (including statics) inside format strings and closes rust-lang#16608.

I'm not sure about adding the `constants` field to the `CompletionContext`. It kinda makes sense, since it's in line with the `locals` field, and this way everything looks a bit cleaner, but at the same time does it really need to be there?

Anyway, let me know if anything should/can be changed. :)

fix: use 4 spaces for indentation in macro expansion

Partial fix for rust-lang#16471.

In the previous code, the indentation produced by macro expansion was set to 2 spaces. This PR modifies it to 4 spaces for the sake of consistency.

Add more methods for resolving definitions from AST to their corresponding HIR types

In order to be able to add these methods with consistent naming I had to also rename two existing methods that would otherwise be conflicting/confusing:

`Semantics::to_module_def(&self, file: FileId) -> Option<Module>` (before)
`Semantics::file_to_module_def(&self, file: FileId) -> Option<Module>` (after)

`Semantics::to_module_defs(&self, file: FileId) -> impl Iterator<Item = Module>` (before)
`Semantics::file_to_module_defs(&self, file: FileId) -> impl Iterator<Item = Module>` (after)

(the PR is motivated by an outside use of the `ra_ap_hir` crate that would benefit from being able to walk a `hir::Function`'s AST, resolving its exprs/stmts/items to their HIR equivalents)

Avoid some allocations

I went on a small `.clone()` hunting tour :D

internal: Clean some stuff up

Just a bunch of small refactorings, mainly from browsing through `hir-def`
