Implement prototype v128.load{32,64}_zero instructions (#3011)

Specified in https://github.com/WebAssembly/simd/pull/237. Since these
are just prototypes necessary for benchmarking, this PR does not add
support for these instructions to the fuzzer or the C or JS APIs. This
PR also renumbers the QFMA instructions that previously used the
opcodes for these new instructions. The renumbering matches the
renumbering in V8 and LLVM.
