When we choose to use zeroinitializer for a trailing portion of an array
constant, don't convert the rest into a packed struct.

If an array constant has a large non-zero portion and a large zero
portion, we want to emit the first part as an array and the rest as a
zeroinitializer if possible. This fixes a memory usage regression from
r333141 when compiling PHP.
