Douglas Yung 774ab60125 Add option to use older clang ABI behavior when passing certain union types as function arguments Recently commit D78699 (commit `26cfb6e562`), fixed clang's behavior with respect to passing a union type through a register to correctly follow the ABI. However, this is an ABI breaking change with earlier versions of the clang compiler, so we should add an -fclang-abi-compat option to address this. Additionally, the PS4 ABI requires the older behavior, so that is added as well. This change adds a Ver11 value to the ClangABI enum that when it is set (or the target is the PS4 triple), we skip the ABI fix introduced in D78699.

// 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:

Information on Clang:             http://clang.llvm.org/

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