void test(long long *P) { *P ^= 1; }

into just:

_test:
	movl	4(%esp), %eax
	xorl	$1, (%eax)
	ret

instead of code like this:

_test:
	movl	4(%esp), %ecx
        xorl    $1, (%ecx)
	movl	4(%ecx), %edx
	movl	%edx, 4(%ecx)
	ret

the code generated is not wonderful.  This turns a miscompilation into
a code quality bug (noted in the ppc readme).  This fixes PR642, which
is over 2 years old (!).  Nate, please review this.
