This is the patch to provide clean intrinsic function overloading support in LLVM. It cleans up the intrinsic definitions and generally smooths the process for more complicated intrinsic writing. It will be used by the upcoming atomic intrinsics as well as vector and float intrinsics in the future. This also changes the syntax for llvm.bswap, llvm.part.set, llvm.part.select, and llvm.ct* intrinsics. They are automatically upgraded by both the LLVM ASM reader and the bitcode reader. The test cases have been updated, with special tests added to ensure the automatic upgrading is supported. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@40807 91177308-0d34-0410-b5e6-96231b3b80d8

For PR1297: Update these test cases to use proper signatures for bswap which is now and overloaded intrinsic. Its name must be of the form llvm.bswap.i32.i32 since both the parameter and the result or of type "iAny". Also, the bit counting intrinsics changed to always return i32. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@35548 91177308-0d34-0410-b5e6-96231b3b80d8
