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.
