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. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@216294 91177308-0d34-0410-b5e6-96231b3b80d8
