As per Ted's advice. It can be brought back from version control if
needed.

This also fixes a Sphinx warning.

The underlying type for an enum should be an integer type, not another enum.

Merge storage classes even when contexts don't match.

This fixes the storage class of extern decls that are merged with file level
statics. The patch also fixes the linkage computation so that they are
considered internal.

test/Misc/dev-fd-fs.c: Mark this as XFAIL:freebsd (since r169831).

I don't want to suppress this to be excluded with the feature "dev-fd-fs". This should work also on freebsd.

Make the format scrambler understand line comments.

This allows for writing tests including line comments easier and more readable.
We will need more of those tests in the future and also line comments are
useful to force line breaks in tests.

CodeGen: Expand creal and cimag into complex field loads

PR 14529 was opened because neither Clang or LLVM was expanding
calls to creal* or cimag* into instructions that just load the
respective complex field.  After some discussion, it was not
considered realistic to do this in LLVM because of the platform
specific way complex types are expanded.  Thus a way to solve
this in Clang was pursued.  GCC does a similar expansion.

This patch adds the feature to Clang by making the creal* and
cimag* functions library builtins and modifying the builtin code
generator to look for the new builtin types.

Better support for constructor initializers.

We used to format initializers like this (with a sort of hacky implementation):
Constructor()
    : Val1(A),
      Val2(B) {

and now format like this (with a somewhat better solution):
Constructor()
    : Val1(A), Val2(B) {

assuming this would not fit on a single line. Also added tests.

As a side effect we now first analyze whether an UnwrappedLine needs to be
split at all. If not, not splitting it is the best solution by definition. As
this should be a very common case in normal code, not exploring the entire
solution space can provide significant speedup.

This is the libclang patch providing minimal API to
use clang's formatter. Currently, formatter is used 
to format declaration tags for xml comments. Since formatter
is in flux and its change will break several of the clang comment
tests, only a single tests is formatted using this facility.
Doug has reviewed and approved it for check-in.
