start 1.5.2 dev
reduce lyra2 blake and pentablake cpu load
x11: small simd512 gpu_expand improvement
simd cleanup
qubit: fix wrong pool difficulty

hmm... this is weird, should be 256 but make bad shares on pool diff 2
lyra2 +100kh for GTX970
Intelligent duplicate shares check

Only enabled on first duplicate share
pentablake: cleanup
uint2: fix SM 3.0 ROR and ROL

Not sure its the fastest way, but it works for offsets 0-63 + 64

Also note than asm SM 3.5+ doesn't support ROR with offset 64
lyra2: cleanup

quickly tested with a SM 3.0 binary...
