i386.c (override_options): Remove ppro, pentium2, and p2 as aliases.

        * i386.c (override_options): Remove ppro, pentium2, and p2 as aliases.
        Default ix86_arch to PROCESSOR_I386.
        * i386.h (CC1_CPU_SPEC): Don't add -march=foo.  Remove -mno-foo.
        (CPP_486_SPEC, CPP_586_SPEC, CPP_686_SPEC): Delete.
        (CPP_CPU_DEFAULT_SPEC): Define to __tune_foo__.
        (CC1_CPU_SPEC): Make -march=foo define __foo__, and provide
        __tune_foo__ if no -mcpu.  Make -mcpu=bar define __tune_bar__.
        (EXTRA_SPECS): Remove deleted specs.
