Lot of SIMD changes... did we write this by hand, or did the upstream spec change in the middle, I'm just curious?

I think we wrote this one by hand as we were implementing SIMD interpretation. That was probably before there were any upstream spec tests.

Updating just one or the other of these tools would cause the tests spec/import-after-*.fail.wast to fail, since only the updated tool would correctly fail to parse its contents. To avoid this, update both tools at once. (The tests erroneously pass before this change because check.py does not ensure that .fail.wast tests fail, only that failing tests end in .fail.wast.) In wasm-shell, to minimize the diff, only use the new parser to parse modules and instructions. Continue using the legacy parsing based on s-expressions for the other wast commands. Updating the parsing of the other commands to use `Lexer` instead of `SExpressionParser` is left as future work. The boundary between the two parsing styles is somewhat hacky, but it is worth it to enable incremental development. Update the tests to fix incorrect wast rejected by the new parser. Many of the spec/old_* tests use non-standard forms from before Wasm MVP was standardized, so fixing them would have been onerous. All of these tests have non-old_* variants, so simply delete them.
