testsuite: Fix input operands of gcc.dg/guality/pr43077-1.c

The type of the output operands *p and *q of the extended asm statement
of function foo is unsigned long whereas the type of the corresponding
input operands is int.  This results, e.g. on IBM Z, in the case that
the immediates 2 and 3 are written into registers in SI mode and read in
DI mode resulting in wrong values.  Fixed by lifting the input operands
to type long.

gcc/testsuite/ChangeLog:

	* gcc.dg/guality/pr43077-1.c: Align types of output and input
	operands by lifting immediates to type long.
