Bug 469225: Move HAVE_ARM_SIMD test after header file tests. r=vladimir

This should have no effect; the test there is in the midst of a
section titled, "Checks for header files", and doesn't belong there.

I've made the same change in both the top-level configure.in and
js/src/configure.in, just to keep things parallel.
