cpuminer-opt-3.7.6 is released.

Added lyra2h algo for Hppcoin.
Added support for more than 64 CPUs.
Optimized shavite with AES, improves x11 etc.

More detailed release notes:

Lyra2h has not been tested. It is virtually a clone of lyra2z so it should work.
Please report any problems.

Support for over 64 CPU is limited in that specifying --cpu-affinity has no effect.
The arg will be ignored and he default affinity will be used. This has not been
tested either so if anyone has the ability to test it please do so and report.

There are no new 4way algos this release but optiizing shavite came as a surprise
and helps all CPUs with AES.

The past two releases have also seen some reworking of some existing SIMD code as
I learn new techniques. It should be more efficient but not likely to produce a significant
speed up.

There are currently 2 4way blockers. BMW is blocking full optimization of x11 and blake256
is blocking m7m. I'd like to get those resolved but I'm stuck at the moment. Since m7m is
CPU only I'd like to prioritize that algo.

A few algos have 4way enabled bur are either untested or have known problems that affect
performance.

Tested working: skein, keccak, keccakc, nist5, tribus.

Enabled untested: skein2, jha, whirlpool, pentablake.

Enabled with known problems: blake256 lane corruption: lyra2z, decred, blake.
These algos operate in 2way mode due to invalid hash in 2 lanes.
