* Take advantage of coercing anonymous struct literals to struct types.
* Reworks Module to favor Zig source as the primary use case.
Breaks ZIR compilation, which will have to be restored in a future commit.
* Decl uses src_index rather then src, pointing to an AST Decl node
index, or ZIR Module Decl index, rather than a byte offset.
* ZIR instructions have an `analyzed_inst` field instead of Module
having a hash table.
* Module.Fn loses the `fn_type` field since it is redundant with
its `owner_decl` `TypedValue` type.
* Implement Type and Value copying. A ZIR Const instruction's TypedValue
is copied to the Decl arena during analysis, which allows freeing the
ZIR text instructions post-analysis.
* Don't flush the ELF file if there are compilation errors.
* Function return types allow arbitrarily complex expressions.
* AST->ZIR for function calls and return statements.
* Introduce the concept of anonymous Decls
* Primitive Hello, World with inline asm works
* There is still an unsolved problem of how to manage ZIR instructions
memory when generating from AST. Currently it leaks.
One of the main motivating use cases for this language feature is
tracing/profiling tools, which expect null-terminated strings for these
values. Since the data is statically allocated, making them
additionally null-terminated comes at no cost.
This prevents the requirement of compile-time code to convert to
null-termination, which could increase the compilation time of
code with tracing enabled.

Branch handling `*[N]T` to `E![]T` is already handled in a more complete
branch handling `*[N]T` to `[]T` *and* `*[N]T` to `E![]T` so it seems
safe to remove this one.
- stderr_file_writer was unused
- stderr_stream was a pointer to a stream, rather than a stream
- other functions assumed that getStderrStream has already been called
