We enable struct.new and array.init initializer expressions in the JS
testcase generated by --wasm-fuzzer-gen-test. We needed to make some
changes in the WasmInitExpr class, and to implement a new interface for
the WasmFullDecoder, which constructs a WasmInitExpr.
Changes:
- Make WasmInitExpr a ZoneObject. Use a pointer for its operands_ field.
This is needed so WasmInitExpr is trivially copiable, and thus usable
as a Value type in WasmFullDecoder.
- Implement a WasmFullDecoder interface in wasm-fuzzer-common that
constructs a WasmInitExpr. Use it to decode initializers in the
module generated by the fuzzer.
- Change AppendInitExpr to take a WasmInitExpr as argument.
- Fix an issue with printing of struct definitions.
- Change initializer expression used for structs to struct.new_with_rtt.
This is consistent with the currently used structural types.

WasmModuleBuilder is a class that is used to build Wasm modules in the
asm.js parser, in the fuzzer, as well as some tests. When it comes to
Wasm tables, WasmModuleBuilder currently supports only basic tables
(before the reftypes proposal) using an ad-hoc indirect-function index
vector.
This CL adds proper support for element sections and tables that use
them in the full potential of the reftypes extension. The new
functionality will only be used in the fuzzer and potentially some tests
in the future. Along this, we drop some functionality from
WasmModuleBuilder that was only used in tests and is redundant with the
new architecture.
Additionally, we remove tables other than externref and funcref from the
fuzzer (which were not supported properly or used anyway). We will
reintroduce them at a later time.

The wasm-compile fuzzer sometimes needs to generate a boolean flag from
the input bytes. Since the general {DataRange::get} method results in
undefined behaviour if instantiated with the {bool} type, we are getting
an 8-bit value instead and looking at the least significant bit only.
This CL improves this situation by implementing a template
specialization for {bool} which uses the same trick, and uses that
instead of hand-coding the modulo operation at the call sites.

We add ref.func and ref.is_null to the fuzzed module.
ref.is_null returns i32, so it is added to i32 generator.
ref.func is added to GenerateOptRef.
GetRefType function is added to generate reftypes.
