MIPS: Reland "Add out-of-line constant pool support to Arm."

Port r20053 (df27abf)

Original commit message:
This CL adds out-of-line constant pool support to Arm. A ConstantPoolBuilder
object is introduced to manage building of the ConstantPoolArray for a given
code object.

This CL depends on the following CLs landing first:
