i386-protos.h (ix86_use_pseudo_pic_reg): New. 

* config/i386/i386-protos.h (ix86_use_pseudo_pic_reg): New.
	* config/i386/i386.h (PIC_OFFSET_TABLE_REGNUM): Simplify by
	using x86_use_pseudo_pic_reg.
	* config/i386/i386.c (ix86_conditional_register_usage): Remove
	support for fixed PIC register.
	(ix86_use_pseudo_pic_reg): Not static any more.
