  [Flang][HLFIR] Relax size check for dot_product intrinsic

If the size of one of the operand arrays is not known at compile
time, do not issue a size mismatch error sinc they could match at
runtime.

Fixes the compilation error in polyhedron/induct2.

  [Flang][HLFIR] Intrinsics: Propagate fast math flags

Add a new FirOpBuilder constructor to propagate the fast math flag
from an operation. Use this constructor in the LowerHLFIRIntrinsics
pass.

This fixes the performance issue with the hlfir intrinsics flow
for polyhedron/test_fpu2.
