Fixes#6926.
If `build` is a subdirectory in the current directory, then `odin build . -out:build` will place `.S`, `.obj` and `.ll` files there if the corresponding `-build-mode` is given.
With ThinLTO, the linker runs sanitizer passes at link time via
-fsanitize= flags, where it has whole-program visibility. Running
them at bitcode emission too double-instruments every module,
producing hundreds of "Redundant instrumentation detected" warnings.
Per-function sanitize/no_sanitize attributes are preserved in the
bitcode and respected by the linker's pass.

- Add -lto:thin and -lto:thin-files CLI flags with validation
- Emit LLVM bitcode (.bc) instead of object files when LTO is enabled
- Pass -flto=thin and -flto-jobs to clang/lld linkers
- Guard linkage corrections to skip declarations without definitions
(required for LTO where declarations appear across modules)
- Allow module-per-file with LTO even at higher optimization levels

- Add intrinsics.objc_super()
- Emit objc_msgSendSuper2 calls when an objc method call is combined with objc_super(self)
- Fix objc_block return value ABI for large struct returns
- Fix objc_implement method wrappers bad ABI for large struct returns and indirect args
- Simplify parameter forwarding for objc_imlpement methods
- Add intrinsics.objc_instancetype to mimi Objective-C instancetype* returns
This facilitates returning the correct type on subclasses when calling mehtods
such as `alloc`, `init`, `retain`, etc.
- Refactor Objective-C class implementations generation so that hierarchies are properly initialized
- Better codegen for context passing with ivar-based autocontext
- Allow @superclass on imported objc-c objects
- Better codegen for block forwarding invoker, arguments are forwarded directly
