Jonas Paulsson 9b38e2efa0 [SystemZ] Fix C++ ABI for passing args of structs containing zero width bitfield.
A struct like { float a; int :0; } should per the SystemZ ABI be passed in a
GPR, but to match a bug in GCC it has been passed in an FPR (see 759449c).

GCC has now corrected the C++ ABI for this case, and this patch for clang
follows suit.

//===----------------------------------------------------------------------===//
// 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 forums:

If you find a bug in Clang, please file it in the LLVM bug tracker:
