I went over the output of the following mess of a command:
`(ulimit -m 2000000; ulimit -v 2000000; git ls-files -z | parallel --xargs -0 cat | aspell list --mode=none --ignore-case | grep -E '^[A-Za-z][a-z]*$' | sort | uniq -c | sort -n | grep -vE '.{25}' | aspell pipe -W3 | grep : | cut -d' ' -f2 | less)`
and proceeded to spend a few days looking at it to find probable typos
and fixed a few hundred of them in all of the llvm project (note, the
ones I found are not anywhere near all of them, but it seems like a
good start).

- Place rules under rule::lhs::rhs__rhs__rhs
- Change mangling of keywords to ALL_CAPS (needed to turn keywords that appear
alone on RHS into valid identifiers)
- Make enums implicitly convertible to underlying type (though still scoped,
using alias tricks)
In principle this lets us exhaustively write a switch over all rules of a NT:
switch ((rule::declarator)N->rule()) {
case rule::declarator::noptr_declarator:
...
}
In practice we don't do this anywhere yet as we're often switching over multiple
nonterminal kinds at once.

- Extend the GLR parser to allow conditional reduction based on the
guard functions;
- Implement two simple guards (contextual-override/final) for cxx.bnf;
- layering: clangPseudoCXX depends on clangPseudo (as the guard function need
to access the TokenStream);

Virtually all LLVM tools accept a `-o` flag, so add one. This will make it
possible to possibly add a --write-if-changed flag later. It also makes it
so that the file isn't partially written if the tool oesn't run successfully.
Marking --grammar as `Required` allows removing some manual
verification code for it.

The main idea is to compile the cxx grammar at build time, and construct
the core pieces (Grammar, LRTable) of the pseudoparse based on the compiled
data sources.
This is a tiny implementation, which is good for start:
- defines how the public API should look like;
- integrates the cxx grammar compilation workflow with the cmake system.
- onlynonterminal symbols of the C++ grammar are compiled, anything
else are still doing the real compilation work at runtime, we can opt-in more
bits in the future;
- splits the monolithic clangPsuedo library for better layering;
