The previous code incorrectly added `sub_path` twice.
Also for the compilation unit, it was passing empty string to realpath,
resulting in the error handling codepath being used.

When analyzing the `validate_ref_ty` ZIR instruction, an assertion would
trip if the result type was a var args function argument. The fix is the
same as e6b73be870a39f4da7a08a40da23e38b5e9613da - inline the logic of
`resolveType` and handle the case of var args.
Closes#17494
When analyzing the `as` ZIR instruction, an assertion would trip if the
result type was a var args function argument. The fix is simple: inline
a little bit of the `resolveType` logic into `analyzeAs` to make it
detect this situation - which it was already attempting to do.
Closes#16197
This makes tmp_directory close before calling renameTmpIntoCache which fixes occurences of those AccessDenied errors that aren't synonymous with PathAlreadyExists on Windows
The following pairs of functions have been combined using the "advanced"
pattern used for other type queries:
* `Sema.fnHasRuntimeBits`, `Type.isFnOrHasRuntimeBits`
* `Sema.typeRequiresComptime`, `Type.comptimeOnly`
This mostly reverts 6e0904504155d3cba80955c108116170fd739aec however it
leaves intact the linker supporting both obj and lib files, and the
frontend choosing which one to create.
When not using libllvm, it means the compiler is not capable of
producing an object file or executable, making the self-hosted backends
be a better default.
Instead of every file deletion being followed by a recursive attempt to
remove the parent directory, while walking the directory, every
directory that will have nonzero files deleted from it is tracked in an
array hash map.
After all the threads have finished deleting and hashing, the parent
thread sorts the "suspicious" directories by length, descending,
ensuring that children appear before parents, and then iterates over the
array hash map, attempting a rmdir operation on each. Any rmdir that
succeeds appends the parent directory to the map so that it will be
removed if empty.
This prevents bogus "error: file exists in multiple modules" errors due
to file paths looking like:
```
note: root of module foo/freetype/
note: root of module foo/fontconfig/../freetype/
```
It also enables checking for dependency paths outside the root package.
* add Module instances for each package's build.zig and attach it to the
dependencies.zig module with the hash digest hex string as the name.
* fix incorrectly skipping the wrong packages for creating
dependencies.zig
* a couple more renaming of "package" to "module"
Only problem is that it looks like `has_build_zig` is being false when
it should be true.
After that is fixed then main.zig needs to create the `@dependencies`
module from the generated source code.
