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. llvm-svn: 216294 2014-08-22 23:59:26 +02:00			`; RUN: llc -mtriple=arm-darwin < %s \| FileCheck %s`
