fix keywords

there should probably be logic to handle all identifiers that start with
__ or with _ followed by a capital letter, rather than special-casing a
bunch of stuff, but for now some c23 keywords were missing and when i
first added keywords i added "nullexpr" instead of "nullptr" lol

Fix phi

Whoops, thanks seb
Fix shifts

And with that, all but one of the Hare stdlib tests pass. The last
failing one is:

math::fround: Assertion failed: /home/ecs/src/hare/hare/math/fenv+x86_64.ha:114:1

and it's due to clang constant-folding the calculations, with the wrong
rounding mode. I don't feel like fixing that, and it's not like it'll
ever affect anyone, so whatever.
