MIPS: o32: provide ta0..ta3 register definitions
This allows to write generic assembly code that will compile under both
o32 and n64 ABIs, as otherwise the register definitions would conflict.
Taken from Linux kernel sources, commit 'MIPS: O32: Provide definition
of registers ta0 .. ta3.' (3ba1e543ab4b02640d396098f2f6a199560d5f2d).
