arm: Add optimized addmul_1
Written from scratch rather than copied from GMP, due to LGPL 2.1 vs
GPL 3, but tested with the GMP testsuite.
This is 25% faster than the generic code as measured on Cortex-A15,
and the same speed as GMP on the same core. It's probably slower
than GMP on the A8 and A9 cores though.
