Fixes a lot of false type mismatches.
(And as always when touching the unification code, I have to say I'm looking
forward to replacing it by Chalk's...)
It's not entirely clear what subnode ranges should mean in the
presence of macros, so let's leave them out for now. We are not using
them heavily anyway.
3996: Fix path for proc-macro in nightly / stable release r=matklad a=edwin0cheng
I messed up that I forget we use different executable names for nightly / stable release, I changed to use the current executable name instead.

4007: Reduce allocations when looking up proc macro decl r=edwin0cheng a=lnicola
`libserde_derive` has about 21K symbols on Linux. It's not much, but let's ~~not be wasteful~~ avoid the allocations anyway.

3958: Add proc-macro related config and tests r=matklad a=edwin0cheng
This PR do the following things:
1. Add cli argument `proc-macro` for running proc-macro server.
2. Added support for proc-macro in bench and analysis-stats
3. Added typescript config for proc-macros
4. Added an heavy test for proc-macros.
To test it out:
1. run `cargo xtask install --proc-macro`
2. add `"rust-analyzer.cargo.loadOutDirsFromCheck": true"` and `"rust-analyzer.procMacro.enabled": true"` in vs code config.
[Edit] Change to use `rust-analyzer proc-macro` for running proc-macro standalone process.

3990: Switch to Chalk recursive solver r=matklad a=flodiebold
Before:
```
Expressions of unknown type: 5526 (3%)
Expressions of partially unknown type: 5415 (3%)
```
After:
```
Expressions of unknown type: 4600 (2%)
Expressions of partially unknown type: 4645 (2%)
```
On the other hand,
```
'./target/release/rust-analyzer analysis-stats -q . # old solver' ran
1.24 ± 0.04 times faster than 'rust-analyzer analysis-stats -q . # new solver'
```
I think part of this just comes from the fact that we're inferring more types now; but apart from that, it should be possible to improve the performance a bunch, and I'll make looking into that a priority.
