[vector] fma, sqrt, pow and broadcast long tests for coverage

[Viswanathan, Sandhya]

Please find below a webrev which adds the following tests:

  1.  fma(float, float) (smoke test only)
  2.  pow(float) (smoke test only)
  3.  pow(vector), sqrt()
  4.  Binary operations with long scalar  (smoke test only)
  5.  Ternary operations with second argument as scalar (smoke test only)
