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.
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.
Entry points need to be attributed with a complete list of
global variables that they use. To that end, the global dependencies
mechanism is extended to also allow functions - when flushing the
module, the list of dependencies is examined to generate this
list of global variable result-ids.
SPIR-V cannot represent function pointers without extensions
that no vendor implements. For the time being, generate a test
kernel for each error, so that we can at least run SOME tests.
In the future we may be able to emulate function pointers in some
way, but that is not today.
