* @workItemId returns the index of the work item in a work group for a
dimension.
* @workGroupId returns the index of the work group in the kernel dispatch for a
dimension.
* @workGroupSize returns the size of the work group for a dimension.
These builtins are mainly useful for GPU backends. They are currently only
implemented for the AMDGCN LLVM backend.
As bpf program has no global section for constant values (especially strings),
so use llvm's builtins (like memcpy, memset, etc) will lead to compilation failure
(something like this: A call to built-in function 'memcpy' is not supported.)

This introduces a new builtin function that compiles down to something that results in an illegal instruction exception/interrupt.
It can be used to exit a program abnormally.
This implements the builtin for all backends.
Many `Type`s can correspond to the same `CType`, so this reduces the
number of used locals by 27760 when compiling only-c.
Also, disabled some tests that were only passing by accident and
shouldn't really be considered working.
After this, the last MSVC warnings are in behavior/bugs/529.zig:
behavior.c(37971): warning C4133: 'function': incompatible types - from 'A__8479 *' to 'A__8474 *'
behavior.c(37974): warning C4133: 'function': incompatible types - from 'A__8480 *' to 'A__8474 *'
* Support always_tail and never_tail/never_inline with a comptime callee using clang
* Support never_inline using gcc
* Support never_inline using msvc
Unfortunately, can't enable behavior tests because of the conditional support.
* Implement @fieldParentPtr on a union
* Refactor field access to ensure that it is handled consistently
* Remove `renderTypecast` as it is now behaves the same as `renderType`
This requires manual defines before C99 which may not have stdint.h.
Also have update-zig1 leave a copy of lib/zig.h in stage1/zig.h, which
allows lib/zig.h to be updated without needing to update zig1.wasm.
Note that since the object already existed with the exact same contents,
this completely avoids repo bloat due to zig.h changes.
