------------------------------------------------------------------------
This CL adds support for decoding eh-related wasm opcodes:
* Throw: used for raising an exception; the thrown value lives on top of
the evaluation stack;
* TryCatch: used to start a try block that has a catch clause;
* TryFinally: used to start a try block that has a finally clause;
* TryCatchFinally: used to start a try block that has both catch and
finally clauses;
* Catch <local>: used to start the catch block of a
TryCatch/TryCatchFinally block; the thrown value is
stored in local <local>; and
* Finally: used to start a finally block of TryFinally/TryCatchFinally.
Three different opcodes are used to start a try block to simplify the
AST construction during bytecode parsing.
