llvm: add pass-by-reference info to debug types
...
Without this data, debugger expressions try to pass structs by-value,
which mostly just crashes.
Also: mark enums as enum classes to prevent the enumerators from
shadowing other identifiers.

llvm: Do not generate static member definitions
...
They were not helping LLDB and actively throwing off GDB.
Also: clean up some llvm.Builder and llvm.ir definitions that are no
longer necessary.

llvm: encode variables as DW_TAG_imported_declaration
...
Now we get working global variable lookup in GDB! LLDB still re-mangles,
and it looks like we can't do much about that for now.
Also: translate non-owning type declarations into typedefs.

llvm: set precise scopes on namespace types and variables
...
This will allow accessing non-local declarations from debuggers, which,
AFAICT, was impossible before.
Getting scopes right already works for type declarations and functions,
but will need some fiddling for variables:
For those, I tried imitating what Clang does for static member
variables, but LLDB tries to re-mangle those and then fails at lookup,
while GDB outright crashes. Hopefully I can find some other dwarven
incantation to do the right thing.

add a debug subcommand for printing LLVM integer type alignment
...
Useful when debugging why upgrading from LLVM 17 to 18 caused C ABI
regressions. Turns out LLVM 18 does the following insane thing:
