Fix a type error in the allocation of non-moving arrays.

Fix a type error in the allocation of non-moving arrays.

Originally, non-moving arrays were allocated with dvmAllocObjectArray.
However, dvmAllocObjectArray does not respect the width of the user
supplied element class and substitutes a hard coded value of 4 bytes.
This change replaces dvmAllocObjectArray with dvmAllocArrayByClass.
dvmAllocArrayByClass consults the element class for its width when
computing the storage size for the array being allocated.
