7b8b9c17db Include 'asm' in the name of X25519 asm sources.
Some build systems don't like two targets with the same base name and
the curve25519 code had x25519-x86_64.[Sc].

77a173efed Add x86-64 assembly for X25519.
This assembly is in gas syntax so is not built on Windows nor when
OPENSSL_SMALL is defined.

fba735cfd8 Register the *25519 tests as dependencies of all_tests.
This ensures the run_tests target updates those binaries.

b1b6229fc8 Add NEON implementation of curve25519.
Nexus 7 goes from 1002.8 ops/sec to 4704.8 at a cost of 10KB of code.
(It'll actually save code if built with -mfpu=neon because then the
generic version can be discarded by the compiler.)
