* Add DWARF debugging information to all artifacts by default
This commit adds DWARF debugging information with the `-g` compiler flag
to all WASI artifacts for wasi-sdk. The LLVM build itself does not have
debugging information, only the sysroot artifacts. This is intended to
assist with debugging. The main downside to this is binary size of
generated artifacts will, by default, be larger. Stripping debug
information from an artifact though involves removing custom sections
which is generally pretty easy to do through wasm tooling.
* Pass extra cflags to wasi-libc
* Fix tests from previous commit
* Update some expected error messages and remove some files with
duplicate error messages that are no longer needed.
* Remove undefined behavior in `stat.c` where padding bytes were being
compared.
This updates the `wasi-libc` submodule to point to `main` and also:
- update tests/testcase.sh to use new wasm32-wasip2 target name
- update various tests/**/*.expected files to match Wasmtime output

This test looks to be asserting that `getrandom` never returns 256
consecutive zeros, but the way it's asserting that is summing up the
bytes and asserting the sum is nonzero. Due to this being a signed
addition, however, it's possible for the bytes to be nonzero and still
trigger the assert. Locally running this test in a loop took 30 or so
seconds before it triggered a failure.
I've updated the test to instead hunt for any entry which is not equal
to zero and then assert that something is not zero.
* build and test `wasm32-wasi-preview2` target
This updates `wasi-libc` to include
https://github.com/WebAssembly/wasi-libc/pull/457, which adds preliminary
support for the new `wasm32-wasi-preview2` target.
It also adds support for testing the new target using Wasmtime 16.0.0 and
`wit-component`. Note that Wasmtime produces different output when reporting
errors for Preview 2 components than it does for Preview 1 modules, so I've
added a few .expected files specific to Preview 2.

This patch enables using latest version of wasmtime for testing. This
should also make it possible to running tests for wasm32-wasi-threads
in the future.
* Add a basic testcase for emulated signals.
* Add a testcase for raise(SIGABRT).
* Fix style.
* Actually use all of the C-standard-required signals.
* Update expected stderr.
* Use the right version of this test file.

To support this, add a mechanism for filtering test output to filter
out uninteresting diffs.
This adds some coverage for the code being changed in
https://github.com/WebAssembly/wasi-libc/pull/184.
wasi-libc builds special versions of printf and other routines optimized
for the case where long double and floating-point in general are not
needed. Ensure that everything still compiles and runs.
This adds a very primitive test harness and tests relevant to the recent
changes to how program startup works, as well as the upcoming changes
to support LTO.
