x86-64: Add vector asinh/asinhf to libmvec microbenchmark

Add vector asinh/asinhf and input files to libmvec microbenchmark.

libmvec-asinh-inputs:
  90% Normal random distribution
  range: (-DBL_MAX, DBL_MAX)
  mean: 0.0
  sigma: 2.0
  10% uniform random distribution in range (-1.0e6, 1.0e6)

libmvec-asinhf-inputs:
  90% Normal random distribution
  range: (-FLT_MAX, FLT_MAX)
  mean: 0.0f
  sigma: 2.0f
  10% uniform random distribution in range (-1.0e6f, 1.0e6f)
