Add an explicit test of the auto-upgrade functionality for the new
intrinsic syntax. Now that this is explicitly covered, I plan to upgrade the existing test suite to use an explicit immediate. Note that I plan to specify 'true' in most places rather than the auto-upgraded value as that is the far more common value to end up here as that is the value coming from GCC's builtins. The only place I'm likely to put a 'false' in is when testing x86 which actually has different instructions for the two variants. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@146369 91177308-0d34-0410-b5e6-96231b3b80d8
