        syssrc/sys/arch/mips/include: regdef.h

Log Message:
Add SGI-compatible ta0-ta3 register names.  These allow one to write
asm code which can be built easily in old-ABI and new-ABI environemnts.

In old-ABI, they map to t4-t7, and in new-ABI, they map to a4-a7.  This
means that t0-t3,ta0-ta3,t8,t9 are available in both ABIs.

Because ta0-ta3 overlap with arg regs (albeit arg slots which are usually
unused), they should be used only if t0-t3,t8,t9 isn't enough.
