tcg: Split helper-proto.h Create helper-proto-common.h without the target specific portion. Use that in tcg-op-common.h. Include helper-proto.h in target/arm and target/hexagon before helper-info.c.inc; all other targets are already correct in this regard.

* Helper file for declaring TCG helper functions.
* This one expands prototypes for the helper functions.

tcg: Invert the inclusion of helper.h Rather than include helper.h with N values of GEN_HELPER, include a secondary file that sets up the macros to include helper.h. This minimizes the files that must be rebuilt when changing the macros for file N. Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Richard Henderson <rth@twiddle.net>

tcg: Use memset for large vector byte replication In f47db80cc07, we handled odd-sized tail clearing for the case of hosts that have vector operations, but did not handle the case of hosts that do not have vector ops. This was ok until e2e7168a214b, which changed the encoding of simd_desc such that the odd sizes are impossible. Add memset as a tcg helper, and use that for all out-of-line byte stores to vectors. This includes, but is not limited to, the tail clearing operation in question.
