Clemens Backes b38c136948 [wasm][inspector][test] Print opcode names 
It makes inspector tests a lot more readable if the opcode of the pause
location is being printed. Since we already have a list of all opcodes
available in wasm-module-builder.js, we can just reuse that to build a
reverse lookup map.

This CL implements this for single-byte opcodes only, which is enough
for all tests that we currently have. It will have to be extended for
prefixed opcodes once that is being used.
