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. llvm-svn: 146369

[opaque pointer type] Add textual IR support for explicit type parameter to gep operator Similar to gep (r230786) and load (r230794) changes. Similar migration script can be used to update test cases, which successfully migrated all of LLVM and Polly, but about 4 test cases needed manually changes in Clang.

[SSP] Remove llvm.stackprotectorcheck. This is a cleanup patch for SSP support in LLVM. There is no functional change. llvm.stackprotectorcheck is not needed, because SelectionDAG isn't actually lowering it in SelectBasicBlock; rather, it adds check code in FinishBasicBlock, ignoring the position where the intrinsic is inserted (See FindSplitPointForStackProtector()). llvm-svn: 265851
