This flips things around such that std/hash/crc.zig is generated
by the catalog-based generation tool, and the real code that used
to be in that file is moved out to std/hash/crc/impl.zig. The
generated tests are moved to std/hash/crc/test.zig. By going this
route, we eliminate the need for usingnamespace without changing
anything for callers of these interfaces. The Crc32 tests are
simply added to the fixed part of the generated output and
compactified a bit.
This was the second-to-last usage of usingnamespace left in std.
`{}` for decls
`{p}` for enum fields
`{p_}` for struct fields and in contexts following a `.`
Elsewhere, `{p}` was used since it's equivalent to the old behavior.
For module parsing and assembling, we will also need to know
all of the SPIR-V extensions and their instructions. This commit
updates the generator to generate those. Because there are
multiple instruction sets that each have a separate list of Opcodes,
no separate enum is generated for these opcodes. Additionally, the
previous mechanism for runtime instruction information, `Opcode`'s
`fn operands()`, has been removed in favor for
`InstructionSet.core.instructions()`.
Any mapping from operand to instruction is to be done at runtime.
Using a runtime populated hashmap should also be more efficient
than the previous mechanism using `stringToEnum`.
This reverts commit da94227f783ec3c92859c4713b80a668f1183f96, reversing

I was against this change originally, but decided to approve it to keep
an open mind. After a year of trying it in practice, I firmly believe
that the previous way of doing it was better.
This reverts commit 0c99ba1eab63865592bb084feb271cd4e4b0357e, reversing
changes made to 5f92b070bf284f1493b1b5d433dd3adde2f46727.
This caused a CI failure when it landed in master branch due to a
128-bit `@byteSwap` in std.mem.
Justification: exec, execv etc are unix concepts and portable version
should be called differently.
Do no touch non-Zig code. Adjust error names as well, if associated.
Closes#5853.
* some manual fixes to generated CPU features code. in the future it
would be nice to make the script do those automatically. I suspect
the sm_90a thing is a bug in LLVM.
* add liteos to various target OS switches. I know nothing about this
OS; someone will need to work specifically on support for this OS
when the time comes to support it properly in zig.
* while waiting for the compiler, I went ahead and made more
conservative choices about when to use `inline` in std/Target.zig
Most of this migration was performed automatically with `zig fmt`. There
were a few exceptions which I had to manually fix:
* `@alignCast` and `@addrSpaceCast` cannot be automatically rewritten
* `@truncate`'s fixup is incorrect for vectors
* Test cases are not formatted, and their error locations change
