Chris Metcalf ce433f8090 tile: avoid undefined behavior with regs[TREG_TP] etc ... Recent compilers warn about accesses to arrays past the end, which is supported for pt_regs and sigcontext with the intended alias past the end of regs[] to sp, tp, and lr using TREG_SP, TREG_TP, and TREG_LR. Make the intended usage explict by providing an anonymous union of regs[56] on the one hand, and a short __regs[53] on the other followed by the sp, tp, and lr fields, so the aliasing is done explicitly and is visible to the compiler.
