v0.8.2

SIMDe 0.8.2

Summary

• Start of RISCV64 optimized implementation using the RVV1.0 vector extension! Thank you @eric900115 @howjmay @zengdage
• 62 of the ARM Neon intrinsics added in SIMDe 0.8.0 had to be removed for not exactly matching the specs and real hardware
  (from the FCVTZS/FCVTMS/FCVTPS/FCVTNS families). This brings us down from 100% coverage of the NEON functions to 99.07%.

X86

There are a total of 6876 SIMD functions on x86, 2930 (43.17%) of which have been implemented in SIMDe so far. Specifically for AVX-512, of the 5160 functions currently in AVX-512, SIMDe implements 1510 (29.26%).

Note: Intel has removed the intrinsics that were unique to Intel Xeon Phi (ER, PF, 4MAPS, and 4VNNIW) from their intrinsic list. SIMDe will retain those few implementations we already had, but this changes how our completeness statistics are calculated.
