  Log Message:
  -----------
  Reimplement constrained 'trunc' using operand bundles

Previously the function 'trunc' in non-default floating-point
environment was implemented with a special LLVM intrinsic
'experimental.constrained.trunc'. Introduction of floating-point operand
bundles allows expressing the interaction with the FP environment using the
same intrinsic as for the default mode.

This changes removes 'llvm.experimental.constrained.trunc' and use
'llvm.trunc' in all cases.
