cSIDH-511: ( #26 )
...
Implementation of Commutative Supersingular Isogeny Diffie Hellman,
based on "A faster way to CSIDH" paper (2018/782).
* For fast isogeny calculation, implementation converts a curve from
Montgomery to Edwards. All calculations are done on Edwards curve
and then converted back to Montgomery.
* As multiplication in a field Fp511 is most expensive operation
the implementation contains multiple multiplications. It has
most performant, assembly implementation which uses BMI2 and
ADOX/ADCX instructions for modern CPUs. It also contains
slower implementation which will run on older CPUs

SHAKE: Don't use function pointers ( #20 )

use unaligned implementation as it's faster (but may crash on some
systems)
* Benchmark compares generic vs unaligned xorIn and copyOut

PERF: sidh-p503: Split sub and add into 2 uops instead of 3 ( #8 )
...
The performance improvement comes from the fact that on Skylake
"add mem, reg" splits into 2 uops - one arithmetic uop and another one
for loading a value from mem.
However, changing operand order to "add reg, mem" splits into 3 uops:
one for arithmetic op, one for load and one additional one for storing
the result back.
Using separated instruction for loading/storing helps to parallelize
execution (load/store and arithmetic instruction is done in parallel
if possible)
For details, see: https://www.agner.org/optimize/instruction_tables.pdf
New: BenchmarkFp503StrongReduce-4 300000000 5.57 ns/op
Old: BenchmarkFp503StrongReduce-4 200000000 8.60 ns/op
This just improves one function, but more functions can be improved

...
* Makefile
* makefile: tools for profiling
* sidh: use SIMD for performing CSWAP
Loads data into 128-bit XMM registers and performs conditional swap.
This is probably less useful for SIDH, but will be useful for cSIDH
