Define PIC_OFFSET_TABLE_REGNUM as INVALID_REGNUM when not compiling PIC.
Also, when compiling PIC, do not force PIC_OFFSET_TABLE_REGNUM to be set
in global_regs[], there is no reason to do this (on the other hand, forcing it
to be set in fixed_regs[] and call_used_regs[] is still necessary and correct).
