41a1ef0dfe implement proper support for _Bool in memory, which is usually i8, not i1. 
This fixes a crash reported by Seo Sanghyeon

65a2288eef More struct bitfields layout work. Now handle, 
struct STestB1 {char a; char b:2; } stb1;
struct STestB2 {char a; char b:5; char c:4} stb2;

e11664a0ef Rename classes and collections that maintain record layout information. 
Now, at AST level record info is maintained by ASTRecordLayout class.
Now, at code gen  level record info is maintained by CGRecordLayout class.

Make target info available to clang code generator.  This is far from complete but this helps clang codegen module make progress.

At the moment target triplet and target description strings are hard coded in clang::TargetInfo
