[WebAssembly] Fix types in wasm_simd128.h and add tests

Authored by tlively on Aug 5 2020, 12:34 PM.



47f7174ffa changed the types used in the Wasm SIMD builtin functions,
but not all of their uses in wasm_simd128.h were updated. This commit
fixes wasm_simd128.h and adds tests to make sure similar problems do
not pass uncaught in the future.

Ah, it seems the reason I didn't see this is that I wasn't using -flax-vector-conversions=none. Thanks for fixing this!


This test currently passes on trunk without the bug fix here. Could you add a -flax-vector-conversions=none line, similar to the C test, which is the case that the patch here fixes?

I think it's ok that this doesn't test with -flax-vector-conversions=none, since that's already tested in the .c file. This pattern of testing is copied from x86intrin.{c,cpp} and that's how this works in those files as well. This .cpp file only exists to additionally test the header contents with extern "C++" around them AFAICT.
