Switch compiler to clang
Clang now is performant enough to use instead of GCC. We can later
switch on ftrapv to better deal with potential problems. Clang was
having problems with BN multiply operations, but it appears to not
affect RSA speeds anymore.
gcc:
openssl speed -elapsed rsa
sign verify sign/s verify/s
rsa 512 bits 0.000759s 0.000073s 1317.5 13621.0
rsa 1024 bits 0.004109s 0.000234s 243.4 4276.1
rsa 2048 bits 0.027652s 0.000842s 36.2 1188.3
rsa 4096 bits 0.198824s 0.003204s 5.0 312.1
clang:
openssl speed -elapsed rsa
sign verify sign/s verify/s
rsa 512 bits 0.000784s 0.000074s 1274.9 13522.6
