pa.c (override_options): Treat TARGET_FAST_INDIRECT_CALLS just like TARGET_NO_SPACE_REGS.

        * pa/pa.c (override_options): Treat TARGET_FAST_INDIRECT_CALLS
        just like TARGET_NO_SPACE_REGS.
        (output_millicode_call): Likewise.
        * pa/pa.h (TARGET_FAST_INDIRECT_CALLS): Define.
        (TARGET_SWITCHES): Add "fast-indirect-calls".
        * pa/pa.md: Treat TARGET_FAST_INDIRECT_CALLS just like
        TARGET_NO_SPACE_REGS in various call/millicode call patterns.
