Erich Keane ac8d1b7017 Enable _rotl, _lrotl, _rotr, _lrotr on all platforms.
The above builtins are currently implemented for MSVC mode, however GCC
also implements these.  This patch enables them for all platforms.

Additionally, this corrects the type for these builtins to always be
'long int' to match the specification in the Intel Intrinsics Guide.

// C Language Family Front-end
//===----------------------------------------------------------------------===//

Welcome to Clang.  This is a compiler front-end for the C family of languages
(C, C++, Objective-C, and Objective-C++) which is built as part of the LLVM
compiler infrastructure project.

Unlike many other compiler frontends, Clang is useful for a number of things
beyond just compiling code: we intend for Clang to be host to a number of
different source-level tools.  One example of this is the Clang Static Analyzer.

If you're interested in more (including how to build Clang) it is best to read
the relevant web sites.  Here are some pointers:

If you have questions or comments about Clang, a great place to discuss them is
on the Clang development mailing list:
