	* config/mips/mips.c (machine_function): Remove
	initialized_mips16_gp_pseudo_p.
	(mips16_gp_pseudo_reg): Use cfun->machine->mips16_gp_pseudo_rtx to
	detect whether a pseudo has already been created.  Unconditionally
	create a new one if not.
	(mips_pic_base_register): Only call mips16_gp_pseudo_reg when
	expanding to rtl.  Create a new pseudo otherwise, if allowed.
