[PATCH] Fix PR77789

[Richard Biener]

This fixes a type error.

Bootstrapped and tested on x86_64-unknown-linux-gnu, applied.

Richard.

2016-10-01  Richard Biener  <rguenther@suse.de>

	PR middle-end/77798
	* genmatch.c (get_operand_type): Add operand position arg
	and handle COND_EXPR comparison operand with fixed boolean_type_node.
	(expr::gen_transform): Adjust.
	(dt_simplify::gen_1): Likewise.

	* gfortran.fortran-torture/compile/pr77798.f90: New testcase.
