pa.c (override_options): Promote -fpic to -fPIC.

        * pa.c (override_options): Promote -fpic to -fPIC.
        (legitimize_pic_address): Simplify due to removal of
        small PIC as a code generation option.
        (secondary_reload_class): Similarly.
        * pa.h (GO_IF_LEGITIMATE_ADDRESS): Similarly.
        (PRINT_OPERAND_ADDRESS): Similarly.
        * pa.md (various patterns): Similarly.
        (small pic lo_sum pattern): Remove.
