[jit] check result_type in gcc_jit_context_new_unary_op

2019-07-22  Andrea Corallo <andrea.corallo@arm.com>

	* jit-recording.c (unary_op_reproducer_strings): Make it extern.
	(binary_op_reproducer_strings): Likewise.
	* jit-recording.h (unary_op_reproducer_strings): Likewise.
	(binary_op_reproducer_strings): Likewise.
	* libgccjit.c (gcc_jit_context_new_unary_op): Check result_type to be a
	numeric type.
	* libgccjit.c (gcc_jit_context_new_binary_op): Improve error message.

2019-07-22  Andrea Corallo <andrea.corallo@arm.com>

	* jit.dg/test-error-gcc_jit_context_new_unary_op-bad-res-type.c:
	New testcase.
	* jit.dg/test-error-gcc_jit_context_new_binary_op-bad-res-type.c:
	Adjust error message.
