It's twenty lines longer, but makes for clearer separation of strict and
reserved keywords (probably a good thing) and removes another moving
part (the definitions of `(STRICT|RESERVED)_KEYWORD_(START|FINAL)`).

Deduplicate in syntax::parse::token with a macro.2013-12-10T22:52:05+00:00Chris Morganme@chrismorgan.info2013-12-10T06:08:48+00:00urn:sha1:267ac45f410e29a8fa52843c9afa58e56cc33479
I also renumbered things at the same time; ``in`` was shifted into its
alphabetical position and the reserved keywords were reordered (a couple
of them were out of order).
Box Block, fn_decl, variant and Ty in the AST, as they were inflating critical enum sizes.2013-11-30T22:00:39+00:00Eduard Burtescuedy.burt@gmail.com2013-11-30T22:00:39+00:00urn:sha1:a9c4b18b18bd3f5fd4a4c20489f37c52d106fc81Register new snapshots2013-11-29T04:27:56+00:00Alex Crichtonalex@alexcrichton.com2013-11-28T20:22:53+00:00urn:sha1:ab387a68388974a432951e806851936898907fd0auto merge of #10670 : eddyb/rust/node-u32, r=alexcrichton2013-11-27T06:07:44+00:00borsbors@rust-lang.org2013-11-27T06:07:44+00:00urn:sha1:faf4c939fb6c55f0b9d19b1292fa4601169b3c17
### Rationale
There is no reason to support more than 2³² nodes or names at this moment, as compiling something that big (even without considering the quadratic space usage of some analysis passes) would take at least **64GB**.
Meanwhile, some can't (or barely can) compile rustc because it requires almost **1.5GB**.
### Potential problems
Can someone confirm this doesn't affect metadata (de)serialization? I can't tell myself, I know nothing about it.
### Results
Some structures have a size reduction of 25% to 50%: [before](https://gist.github.com/luqmana/3a82a51fa9c86d9191fa) - [after](https://gist.github.com/eddyb/5a75f8973d3d8018afd3).
Sadly, there isn't a massive change in the memory used for compiling stage2 librustc (it doesn't go over **1.4GB** as [before](http://huonw.github.io/isrustfastyet/mem/), but I can barely see the difference).
However, my own testcase (previously peaking at **1.6GB** in typeck) shows a reduction of **200**-**400MB**.
