Add ARM assembly implementation of SHA-512
* cipher/Makefile.am: Add 'sha512-arm.S'.
* cipher/sha512-arm.S: New.
* cipher/sha512.c (USE_ARM_ASM): New.
(_gcry_sha512_transform_arm): New.
(transform) [USE_ARM_ASM]: Use ARM assembly implementation instead of
generic.
* configure.ac: Add 'sha512-arm.lo'.

Benchmark on Cortex-A8 (armv6, 1008 Mhz):
Before:
| nanosecs/byte mebibytes/sec cycles/byte
SHA512 | 112.0 ns/B 8.52 MiB/s 112.9 c/B
After (3.3x faster):
| nanosecs/byte mebibytes/sec cycles/byte
SHA512 | 34.01 ns/B 28.04 MiB/s 34.28 c/B
