Nevermind that.  I realized I could reproduce the bug without any ARM-specific code at all.  I added a testcase in svn 110935.  Thanks for prodding me to think about it some more!

We run the FrontendC tests with the host compiler, which for me is x86.  I only have ARM cross compilers.  The testcase is also specific to NEON.  I might be able to come up with something that only requires VFP instead of NEON, but I don't know of a way to make a FrontendC test conditional on details of the target like that.
