Some linux headers use __signed__ for whatever reason.. this is a
general fix for those alternate keyword

Interned strings are used pervasively, so it's a good idea to add a
layer of type safety to differentiate them from general cstrs and avoid
potential bugs from comparing non-interned and interned strings. Not
that that's happened so far that I can remember, but it could.
I'm 90% sure it's legal to alias `struct {char c;}` pointers with `char`
pointers. This specific typedef gives type safety but with a simple
one-way `internstr -> const char *` typecast (with `&istr->c`).
Converting the other way around is more intentional: a straight up cast
`(internstr)cstr` which sticks out as unchecked and probably wrong, or
calling the intern(cstr) function, which is the right way.

Being in lex.c was vestigial, since it was being used all over the
frontend and backend.
lex: use pmap for macro lookup2025-12-12T09:21:43+00:00lemonlsof@mailbox.org2025-12-12T09:20:39+00:00urn:sha1:5f0793c34c4f10a2221b793316fdc82c50d10452
To reduce hashmap code repetition. Also add pmap_del for this purpose
