When we lower the instruction for `@tagName` we generate a new
function if it doesn't exist yet for that decl. This function creates
an if-else chain to determine which value was provided. Each tag
generates a constant that contains its name as the value. For each
tag we generate a case where the pointer of the string is stored in
the result slice. The length of the tagname is comptime-known, therefore
will be stored in the slice directly without having it being part of
the tagname symbol. In the future this can use a jump table instead
of an if-else chain, similar to the `switch` instruction.

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.
