[pushed] testsuite, objective-c: Fix a testcase on Windows.

[Iain Sandoe]

tested by 'nightstrike' on Windows, and on x86_64-darwin21,
pushed to master, thanks,
Iain

Windows needs to use uintptr_t to represent an integral pointer type (long
is not the right type there).

Patch from 'nightstike'.

Signed-off-by: Iain Sandoe <iain@sandoe.co.uk>

gcc/testsuite/ChangeLog:

	* obj-c++.dg/proto-lossage-4.mm: Use uintptr_t for integral pointer
	representations.
