stage2: implement structs in the frontend
New ZIR instructions:
* struct_decl_packed
* struct_decl_extern
New TZIR instruction: struct_field_ptr
Introduce `Module.Struct`. It uses `Value` to store default values and
abi alignments.
Implemented Sema.analyzeStructFieldPtr and zirStructDecl.
Some stuff I changed from `@panic("TODO")` to `log.warn("TODO")`.
It's becoming more clear that we need the lazy value mechanism soon;
Type is becoming unruly, and some of these functions have too much logic
given that they don't have any context for memory management or error
reporting.
