The DCHECK in the lookup method compares the stashed length of the backing store
and the byte_length queried on lookup. These two are not guaranteed to be equal
as there can be grow calls that update the lenght of the buffer between the

When loading a 32-bit value from the stack, just load 32 bit and
zero-extend them into the target register, instead of loading the full
64 bits.

As there are things to fix (see https://crbug.com/1356461), we only
enable this optimization for Wasm for now.

Since fast api calls can now also call back to JS there can be
multiple active fast c calls at the same time. This means just
checking Isolate::InFastCCall() is not enough anymore because this
only returns the state of the last CEntry frame.

This CL therefore disables code space compaction when a stack is
present to allow for multiple/nested fast C calls. Alternatively
we could also just e.g. pin code objects referenced from the stack but
this would require a bit more work.
