target-hppa: Add nullification framework The HPPA cpu has a unique form of predicated execution in which almost any instruction can set the PSW[N] (or "nullify") bit, which suppresses execution (and even decoding) of the following instruction. Execution of a nullified insn clears the PSW[N] bit. This adds a generic framework for branching over nullified insns, or for sufficiently simple insns, transforming the writeback of the result to a conditional move. In the process, we want to be able to represent PSW[N] as a TCG condition, which implies management of the related tcg temps. Signed-off-by: Richard Henderson <rth@twiddle.net>

target-hppa: Add framework and enable compilation This is just about the minimum required to enable compilation without actually executing any instructions. This contains the HPPACPU structure and the required callbacks, the gdbstub, the basic translation loop, and a translate_one function that always results in an illegal instruction.
