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.)

b2c312d670 curve25519: fiat-crypto field arithmetic. 
Each operation was translated from fiat-crypto output using fiat-crypto
prettyprint.py. For example fe_mul is synthesized in
https://github.com/mit-plv/fiat-crypto/blob/master/src/Specific/X25519/C32/femul.v,
and shown in the last Coq-compatible form at
https://github.com/mit-plv/fiat-crypto/blob/master/src/Specific/X25519/C32/femulDisplay.log.
