d6e68f4334 Reland "[deoptimizer] Use empty fixed array when materializing empty arguments elements." 
This reverts commit 917b9cb9fc.

In this CL, we canonicalize the fixed array when allocating storage for
empty fixed array. During initialization, we also make sure that we do
not write to the empty fixed array. This is quite hacky, but it
seems to be the least intrusive change.
