cpu_has_eflag(): mark output registers as earlyclobbers
We assign values to the output registers before the input operand is used, so we have to use =&r to make sure the input operand isn't clobbered. Note: "ri" is correct; it cannot safely be a memory operand, because the stack pointer isn't where the compiler would expect it to be. Signed-off-by: H. Peter Anvin <hpa@zytor.com>
