We forgot to check if a load's input node (index) has any replacement.
This led to weird cases like I32x4ExtractLane persisting even after
scalar lowering is done, which is incorrect.
This manifested in a crash, where we try to call pextrd with a general
register operand.
With this, we can run all currently checked in performance tests without
crashing.

This change completes the necessary API changes for import assertions
discussed in
https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY.
The old ResolveCallback is deprecated and replaced with a
ResolveModuleCallback that includes import assertions. Until
ResolveCallback is removed, InstantiateModule and associated functions
are modified to accept both types of callback, using the new one if it
was supplied and the old one otherwise. An alternative that I chose not
to go with would be to just duplicate InstantiateModule and associated
functions for both callback types.
SyntheticModule::PrepareInstantiate's callback parameter was unused so I
removed it.

The streaming decoder computed the code section start from the passed
"offset". That offset is computed from the module offset *after* the
number of functions has been read. Hence 1 is subtracted, with the
comment:
// The offset passed to {ProcessCodeSectionHeader} is an error offset and
// not the start offset of a buffer. Therefore we need the -1 here.
That subtraction of 1 worked when the number of functions was encoded in
a 1-byte LEB, otherwise it was off.
This CL fixes the immediate issue of passing the right code offset. The
usage of the previously existing offset also seems wrong, and I will try
to clean that up in a follow-up CL.

ScopeInfo objects generally start with three fields: flags, parameter
count, and local variable count. But a single read-only ScopeInfo
instance has none of those fields. This is the empty ScopeInfo, which is
used for contexts that don't correspond to any scope (the native context
and contexts for builtin functions). Since there is only ever a single
instance of the empty ScopeInfo, the memory savings of omitting these
fields is trivial, and we can simplify logic somewhat by including them.
Rather than checking for length to be zero, this change introduces a new
flag indicating that a ScopeInfo instance is the empty one.
On its own, this change doesn't provide a whole lot of value. However,
it sets us up for two further improvements, which are consistent with
the goals outlined in [1]:
1. We should fully describe ScopeInfo fields in Torque. Getting rid of
the requirement to check for emptiness would substantially simplify the
indexed field expressions.
2. ScopeInfo shouldn't inherit from FixedArray, and shouldn't begin with
a `length` field when the length can be computed from the other fields.
This would save a small amount of heap memory and avoid any possibility
of a mismatch between the two ways of computing the length.

analogy to const and mutable references, which we already have.
A const slice as a readonly view into memory, it doesn't mean that
nobody else has a writable view on it.
An array field in a Torque class produces const slices if it is declared

Due to limitations in the Torque type system, mutable slices are not
a subtype of const slices of the same type.
