OpenBSD 7.3 changed its implementation of
pthread_get_name_np/pthread_set_name_np to wrap new libc functions
getthrname/setthrname and lowered the max buffer size from 32 to 24.
This is not a backwards-compatible change because if we were to put in
comptime version logic to use size 32 when target < 7.3 the binaries
would be undefined when running on >= 7.3. It also could simply be that
OpenBSD has a policy to not support older binaries running on newer
releases? Regardless, the safest course is to simply use the smallest
known buffer size.
As an aside, this bug manifested as a "hung" std.Thread test because 7.3
pthread API never checks for error result when wrapping getthrname/setthrname.
This is not a problem in std.Thread when we use the correct max buffer
size because ERANGE/EINVAL become unreachable.

* remove setName, setFilter, and setTestRunner. Please set these
options directly when creating the CompileStep.
* removed unused field
* remove computeOutFileNames and inline the logic, making clear the
goal of avoiding state mutations after the build step is created.
These functions are problematic in light of dependencies because they
run and install, respectively, for the *owner* package rather than for
the *user* package. By removing these functions, the build script is
forced to provide the *Build object to associate the new step with,
making everything less surprising.
Unfortunately, this is a widely breaking change.

This was used to ensure that an artifact would only be installed once,
but this is not only unnecessary, but actively harmful, in the face of
dependencies.

Support for the built-in libcrypt was removed in commit 6b7ddfba,
but the -lcrypt flag remained ignored, preventing linking against
external libcrypt.
Fixes#5990.

In order to be able to report nice errors in the test runner, and in order
to check SkipZigTest errors, we need to pass the error names to the consumer.
This kind of information can be passed via nonsemantic instructions - using
OpSourceExtension here.
All errors are concatenated into a single string, starting with 'zig_errors:'
for identification, separated by a colon (:). To ensure that we can represent
all error codes, even those which contain a colon, the error names are URI-
escaped. URI-escaping, rather than base64, allows us to see the error names
when viewing disassembled SPIR-V code.
It seems that some implementations may have problems with these right now,
like Intel and Rusticl. In theory, these attributes should be superficial
on the pointer type, as alignment guarantees are also added via the
alignment option of the OpLoad and OpStore instructions. Therefore, get rid
of them for now.
For SPIR-V, only export the main function if it is actually declared. Kernel
entry points will often have parameters and more than one kernel declared.
In general, SPIR-V binaries should mostly be compiled as libraries and not as
executables. However, this start code is required so that we can build test
executables.
Note that a call to isSpirV() would emit the code for that function, even though
the call is at comptime. To save that function from being emitted the checks
are just inlined manually.
AmdgpuKernel and NvptxKernel are unified into a Kernel calling convention.
There is really no reason for these to be separate; no backend is allowed to
emit the calling convention of the other. This is in the same spirit as the
.Interrupt calling convention lowering to different LLVM calling conventions,
and opens the way for SPIR-V kernels to be exported using the Kernel calling
convention.
