stage2: prevent UB in the LLVM backend
* Sema: fix `zirTypeInfo` allocating with the wrong arenas for some
stuff.
* LLVM: split `airDbgInline` into two functions, one for each AIR tag.
- remove the redundant copy to type_map_arena. This is the first
thing that lowerDebugType does so this hack was probably just
accidentally avoiding UB (which is still present prior to this
commit).
- don't store an inline fn inst into the di_map for the generic
decl.
- use a dummy function type for the debug info to avoid whatever UB
is happening.
- we are now ignoring the function type passed in with the
dbg_inline_begin and dbg_inline_end.
* behavior tests: prepare the vector tests to be enabled one at a time.
Mitigates #11199.
