David Benjamin 32e59d2d32 Switch to new fiat pipeline. 
This new version makes it much easier to tell which code is handwritten
and which is verified. For some reason, it also is *dramatically* faster
for 32-bit x86 GCC. Clang x86_64, however, does take a small hit.
Benchmarks below.

x86, GCC 7.3.0, OPENSSL_SMALL
(For some reason, GCC used to be really bad at compiling the 32-bit curve25519
code. The new one fixes this. I'm not sure what changed.)
