  Log Message:
  -----------
  [Hexagon] Add an option to use fast FP to int convert for some HVX cases (#169562)

Lowering several flavors of fptosi for HVX can be done faster, but
violates c/c++ convention on some arch tags. Nevertheless customers are
using direct intrinsics with "incorrect" rounding mode and want compiler
to do the same.

Default behavior is not changed.
