This takes the code that was previously in src/Compilation.zig to turn resinator diagnostics into Zig error bundles and puts it in resinator/main.zig, and then makes resinator emit the resulting error bundles via std.zig.Server (which is used by the build runner, etc). Also adds support for turning Aro diagnostics into ErrorBundles.
This moves .rc/.manifest compilation out of the main Zig binary, contributing towards #19063
Also:
- Make resinator use Aro as its preprocessor instead of clang
- Sync resinator with upstream
Fixes compilation errors in functions that are syntaxic sugar
to operate on serialized scalars.
Also make it explicit that square roots in fields whose size is
not congruent to 3 modulo 4 are not an error, they are just
not implemented yet.
Reported by @vitalonodo - Thanks!
A lot of these "shorthand" doc comments were redundant, low quality
filler content. Better to let the actual modules speak for themselves
with top level doc comments rather than trying to document their
aliases.
* `linux.IO_Uring` -> `linux.IoUring` to align with naming conventions.
* All functions `io_uring_prep_foo` are now methods `prep_foo` on `io_uring_sqe`, which is in a file of its own.
* `SubmissionQueue` and `CompletionQueue` are namespaced under `IoUring`.
This is a breaking change.
The new file and namespace layouts are more idiomatic, and allow us to
eliminate one more usage of `usingnamespace` from the standard library.
2 remain.
Some of the structs I shuffled around might be better namespaced under
CONTEXT, I'm not sure. However, for now, this approach preserves
backwards compatibility.

Thanks to Zig's lazy analysis, it's fine for these symbols to be
declared on platform they won't exist on. This is already done in
several places in this file; e.g. `pthread` functions are declared
unconditionally.
Eliminates one more usage of `usingnamespace` from the standard library.
4 remain.
Searching GitHub indicated that the only use of these types in the wild is
support in getty-zig, and testing for that support. This eliminates 3 more uses
of usingnamespace from the standard library, and removes some unnecessarily
complex generic code.
This usage of `usingnamespace` was removed fairly trivially - the
resulting code is, IMO, more clear.
Eliminates one more usage of `usingnamespace` from the standard library.
This is a trivial change - this code did `usingnamespace` into an
otherwise empty namespace, so the outer namespace was just unnecessary.

This fixes an issue with the implementation of #18816. Consider the
following code:
```zig
pub fn Wrap(comptime T: type) type {
return struct {
pub const T1 = T;
inner: struct { x: T1 },
};
}
```
Previously, the type of `inner` was not considered to be "capturing" any
value, as `T1` is a decl. However, since it is declared within a generic
function, this decl reference depends on the context, and thus should be
treated as a capture.
AstGen has been augmented to tunnel references to decls through closure
when the decl was declared in a potentially-generic context (i.e. within
a function).
This changes the representation of closures in Zir and Sema. Rather than
a pair of instructions `closure_capture` and `closure_get`, the system
now works as follows:
* Each ZIR type declaration (`struct_decl` etc) contains a list of
captures in the form of ZIR indices (or, for efficiency, direct
references to parent captures). This is an ordered list; indexes into
it are used to refer to captured values.
* The `extended(closure_get)` ZIR instruction refers to a value in this
list via a 16-bit index (limiting this index to 16 bits allows us to
store this in `extended`).
* `Module.Namespace` has a new field `captures` which contains the list
of values captured in a given namespace. This is initialized based on
the ZIR capture list whenever a type declaration is analyzed.
This change eliminates `CaptureScope` from semantic analysis, which is a
nice simplification; but the main motivation here is that this change is
a prerequisite for #18816.
fill(0) will fill all bytes in bit reader. If bit reader is aligned to
the byte, as it is at the end of the stream this ensures no overshoot
when reading footer. Footer is 4 bytes (zlib) or 8 bytes (gzip). For
zlib we will use 4 bytes BitReader and 8 for gzip. After align and fill
we will read those bytes and leave BitReader empty after that.
* Introduce `-Ddebug-extensions` for enabling compiler debug helpers
* Replace safety mode checks with `std.debug.runtime_safety`
* Replace debugger helper checks with `!builtin.strip_debug_info`
Sometimes, you just have to debug optimized compilers...
