When a function returns multiple result, we check the only the first
result. We correctly get the first return value from the interpreter
results, but did not handle the compiled code correctly, which returns a
JSArray.

Scopes in V8 are used to guarantee one or more properties during its
lifetimes. If a scope is not named e.g MyClassScope(args) instead of
MyClassScope scope(args) it will get created and automatically destroyed
and therefore, being useless as a scope. This CL would produce a
compiling warning when that happens to ward off this developer error.

This CL prepares the interpreter for 64-bit addresses. The offset (in
the memory immediate) can now be 64-bit, and also the index (from the
stack) will be 64-bit if memory64 is enabled.
memory.size will return a 64-bit constant under memory64.
memory.grow is a bit more involved and requires more refactorings in the
called functions. I left a TODO in the interpreter for now.

This is a first small step for implementing the memory64 proposal:
1. Add a feature flag.
2. Add the 0x04 and 0x05 limits flag for memory64.
3. Read memory limits as LEB-encoded u64 (instead of u32) if a memory64
limit flag was read.
4. Unify {MaximumFlag} and {MemoryFlag}, which was used inconsistently
before.
5. Add test for memory limits encoded with >5 bytes.
6. Move some macros from module-decoder-unittest.cc to wasm-macro-gen.h.
Note that still the same limits for the maximum number of pages applies
as before, i.e. you cannot specify a memory >4GB yet. But you can encode
that small number in >5 bytes.

Instantiating a module that contains a function (exported) with a v128
in its signature is fine, but then later calling it will trap.
So v128 values are technically not callable from JS, but we can give it
a default argument of 0, and will later trap anyway. This is useful when
fuzzers generate functions with v128 in the signature of the main
function that we then later try to call.

For "else" and "catch" statements, the Ref to the end label should only
be added if the current block is unreachable, not the parent block.
In the added regression test, the "true" block ends in an unreachable
state with a stack height less than the target height of the end label.
This is valid due to the semantics of unreachable code, but we should
not add the Ref in this case because its stack height is invalid.

Functions with v128 in their signatures are always lowered to 4 word32.
So if a return happens to be have an input that is a f32x4 operation, we
get a register allocator error because it tries to fit a float into a
general register. To fix that we need to do some checks when lowering
kReturn, and for each input node, if we are returning a v128, and it is
to be lowered into 4 f32 nodes, we bitcast the floats to ints.

The fuzzers were calling the compiled function without passing explicit
arguments. Thus all arguments were converted from the "undefined" value,
which typically results in a zero value, as expected.
For BigInt though, it's not allowed to pass "undefined". We have to pass
a proper BigInt.
This CL implements this by passing explicit parameter values for all
parameters.
This effectively unlocks testing BigInt parameters in all fuzzers, thus
may increase coverage and find new bugs.
