Hi!

In this case we create
  temp = .MUL_OVERFLOW (arg1, arg2);
  temp2 = REALPART_EXPR <temp>;
  temp3 = IMAGPART_EXPR <temp>;
x86 has been happy in the testing even without the following patch,
though temp hasn't been rewritten into SSA, but on various other targets
the expansion assumes that .???_OVERFLOW result must be a SSA_NAME.

Fixed thusly, bootstrapped/regtested on x86_64-linux and i686-linux,
committed to trunk.

	PR tree-optimization/91074
	* omp-low.c (lower_omp_for_scan): Set DECL_GIMPLE_REG_P on cplx
	temporary.
