jonathan 34ab2734da Resolve all differences between the Pica and pmax versions of machConst.h:
* add "MIPS_3k_" for the MIPS-I r[23]000-specific register definitions.
    * add "MIPS_4k_" for the MIPS-II/III r4000-specific register definitions.
    * add #defines that provide the old values for locore and user
      code, so the existing code continues  to compile.

Regression-tested against the  old headers by grepping for #define's,
editing out the defined symbols, and preprocessing with both the previous
machConst.h headers and this version.

Some unused symbols (CPU and FPU must-be-zero constants) are no longer defined.
Pica interrupt masks are now constant expressions instead of constant
values.

TODO:
    * factor out the common #defines into src/sys/arch/mips.
    * Get rid of the Sprite coding-style names (MACH_xxx).
    * Separate out the r3k/r4k differences from the Pica/pmax differences.
    * Figure out how to have a run-time choice of r3k vs. r4k support,
     instead of a compile-time choice.
