Alexander Markov 707cd928af [vm/ffi] Fix representation of value for 8-bit and 16-bit FFI loads and stores 
Previously, FFI store could use kUnboxedUint32 for value being stored
via 8-bit or 16-bit StoreIndexed instruction. However, such
StoreIndexed instructions require kUnboxedIntPtr representation.
Due to the mismatch in the representations, SelectRepresentations
pass inserts a speculative (deoptimizing) IntConverter instruction,
which cases crash in AOT mode. Similar problem exists for FFI loads.

This change corrects representation when unboxing value in the body
of FFI store intrinsics and when boxing the value in FFI loads,
so representation of the value matches representation required by
StoreIndexed / returned by LoadIndexed.
