It splits the login of actual instruction emission away from the logic that figures out the appropriate sequence on AArch64ExpandPseudo::expandMOVImm. The new function AArch64_IMM::expandMOVImm, which return the list of the instructions to materialize the immediate constant, is implemented on a separated unit because it will be used in a subsequent patch to optimize floating point materialization.
