Merge with WebAssembly/spec (#19)

* [test] Adjust br_table length test to avoid wrong failure (WebAssembly#1715)

* [spec] Fix extmul & extadd execution (WebAssembly#1716)

* [interpreter] Add dune dependencies (WebAssembly#1717)

* Revert "[interpreter] Add dune dependencies (WebAssembly#1717)"

This reverts commit 44ed035.

* [interpreter/test] Fix inconsistent use of float values in `spectest` (WebAssembly#1718)

* [spec] Fix operand order in reduction of shape.replace_lane (WebAssembly#1721)

* [spec] Fix sx to be sx? in reduction of vcvtop_zero (WebAssembly#1720)
