This commit includes a mention of the landingpad instruction, but it's not
changing the behavior around it. I think the current behavior is correct,
though. Bill, can you double-check that?

Avoid evaluating Neon macro arguments more than once by disabling type checks.
...
It turns out that the use of "__extension__" in these macros was disabling
the expected "incompatible pointer" warnings, so these type checks were not
doing anything anyway. They introduced a serious bug by evaluating some
macro arguments twice, which is a big problem for arguments with side effects.
I'll have to find another way to get the right type checking. Radar 9947657.
