re PR fortran/31120 ([4.1/4.2 only] ICE with integer_exponentiation_1.f90 and -ffast-math) 

	PR fortran/31120

	* trans-expr.c (gfc_conv_powi): Make n argument unsigned hwi.
	(gfc_conv_cst_int_power): Handle integer exponent with care,
	since it might be too large for us.

	* gfortran.dg/integer_exponentiation_2.f90: New test.
