[PATCH, committed] Fix int vs bool issue in jit.dg/test-arith-overflow.c

[David Malcolm]

This jit testcase was failing on s390x and ppc64 due to
carelessly assuming int==bool.

Patch fixes the testcase on s390x and ppc64.  Also tested on
x86_64 and aarch64.

Committed to trunk as r219856.

gcc/testsuite/ChangeLog:
	* jit.dg/test-arith-overflow.c: Include stdbool.h.
	(create_overflow_fn): Update comment to clarify that
	the third param of the created function is a bool *, not
	an int *.
	(verify_int_overflow_fn): Convert param "expected_ovf" from
	int to bool.  Update third param of "overflow_fn_type" from int *
	to bool *.  Update local "actual_ovf" from int to bool.
	(verify_uint_overflow_fn): Likewise.
