This instruction is a non-standard V8-only experiment for now,
hidden behind the --experimental-wasm-gc-experiments flag.
The motivation is to provide a way to set up non-canonicalized
RTT hierarchies, to enable expressing the type system of Java-like
languages in terms of WasmGC constructs.

The typing of br_table was relaxed in
https://github.com/WebAssembly/spec/pull/1305. Before, we had to compute
the greatest lower bound of all branch types and make sure that stack
values are subtypes of that type. Now, we have to check that the stack
values are subtypes of each individual branch. This makes a difference
only in polymorphic stacks, but greatly simplifies the code, especially
with the upcoming introduction of a much more complex type system in
wasm-gc.

First step towards the new exception handling proposal:
https://github.com/WebAssembly/exception-handling/issues/125
This is essentially a revert of:
"[wasm] Switch to new 'catch' and 'br_on_exn' proposal."
The changes are:
- "catch" instruction takes a tag immediate,
- "rethrow" instruction takes a label immediate,
- Add "catch_all" instruction,
- Remove "br_on_exn" instruction,
- Do not push exceptions on the stack, only the encoded values

read_heap_type did not have knowledge of the module for which the heap
type was being decoded. As a result, callers of read_heap_type (or
read_value_type, which in turn calls read_heap_type) had to check after
the fact that a decoded indexed type (ref, ref null, or rtt) references
a type index within the module's bounds. This was not done consistently,
and was missing (at least) in DecodeLocals.
To avoid such problems in the future, this CL refactors read_heap_type
to accept a module and check the decoded index against it.
Changes:
- Add WasmModule argument to read_heap_type. Do so accordingly to all
its transitive callers (read_value_type, immediate arguments,
DecodeLocalDecls, DecodeValue/HeapType in unittests).
- Add index check to read_heap_type and emit an error for an
out-of-bounds index.
- Remove all other now-redundant index validations. Replace them with
decoder->ok() if needed (since read_heap_type will now emit an error).
- Fix error message in Validate for BlockTypeImmediate.
- In DecodeLocalDecls in unittests, pass an empty module to
DecodeLocalDecls in the main code.
- Add a unit test with an invalid index in local type declarations.

If DecodeLocals exits early, num_locals_ is left in an inconsistent
state. This CL fixes this issue by updating num_locals_ as the
local_types_ are updated.

After preparing Liftoff, TurboFan, and the interpreter for this change,
we now store the memory offset as uint64_t. {LoadLane} and {StoreLane}
were added after the TurboFan refactoring, so those two are adapted
similar to the other memory operations.

Before adding more tests, refactor the (single) existing test to be
parameterized by the memory type. This makes it easier to write a single
test with different expectations on memory32 and memory64.
