Alex Crichton 9c6884e28d Update the spec reference testsuite submodule (#3450)
* Update the spec reference testsuite submodule

This commit brings in recent updates to the spec test suite. Most of the
changes here were already fixed in `wasmparser` with some tweaks to
esoteric modules, but Wasmtime also gets a bug fix where where import
matching for the size of tables/memories is based on the current runtime
size of the table/memory rather than the original type of the
table/memory. This means that during type matching the actual value is
consulted for its size rather than using the minimum size listed in its
type.

* Fix now-missing directories in build script
