Don't swap function decls, and add them to the scope as they are
...
encountered. Mixing up the decls is unintuitive, and confuses the AST
destruction code. Fixes PR2360.
Note that there is a need to look up the characteristics and
declarations of a function associated with a particular name or decl,
but the original swapping code doesn't solve it properly.
http://lists.cs.uiuc.edu/pipermail/cfe-dev/2008-May/001644.html is one
suggestion for how to fix that.

Fix support for _Bool bitfields. The issue is that the bitfield width
...
used for _Bool is not the same as the primitive width (which for _Bool
is 1 bit). The load and store changes add some casts to make the
types consistent. The EmitLValue changes make sure that the pointer is
of an appropriate type for loading the bitfield.
This isn't perfect, but it's an improvement, and getting everything
right depends on actually laying out structs in an ABI-compliant way.
