Reid Kleckner 2d9bb65b3d ARM / x86_64 varargs: Don't save regparms in prologue without va_start ...

There's no need to do this if the user doesn't call va_start. In the
future, we're going to have thunks that forward these register
parameters with musttail calls, and they won't need these spills for
handling va_start.

Most of the test suite changes are adding va_start calls to existing
tests to keep things working.
