5fb5df9c83 Restructure how the driver communicates information about the 
target Objective-C runtime down to the frontend:  break this
down into a single target runtime kind and version, and compute
all the relevant information from that.  This makes it
relatively painless to add support for new runtimes to the
compiler.  Make the new -cc1 flag, -fobjc-runtime=blah-x.y.z,
available at the driver level as a better and more general
alternative to -fgnu-runtime and -fnext-runtime.  This new
concept of an Objective-C runtime also encompasses what we
were previously separating out as the "Objective-C ABI", so
fragile vs. non-fragile runtimes are now really modelled as
different kinds of runtime, paving the way for better overall
differentiation.

As a sort of special case, continue to accept the -cc1 flag
-fobjc-runtime-has-weak, as a sop to PLCompatibilityWeak.

I won't go so far as to say "no functionality change", even
ignoring the new driver flag, but subtle changes in driver
semantics are almost certainly not intended.

d5321247c4 Add a -rewrite-includes option, which is similar to -rewrite-macros, but only expands #include directives.

(I was going to fix the TODO about DenseMap too, but
that would break self-host right now. See PR11922.)

623e8778c1 In FixItRewriteToTemp::RewriteFilename don't try to close the file descriptor 
with close(); return it instead.

Fixes mingw build and eliminates possible racing issues.

24e9afff43 Introduce 3 new fixit options: 
-fixit-recompile
	applies fixits and recompiles the result
-fixit-to-temporary
	applies fixits to temporary files
-fix-only-warnings">,
    applies fixits for warnings only, not errors

Combining "-fixit-recompile -fixit-to-temporary" allows testing the result of fixits
without touching the original sources.

c1b1729b66 Break Frontend's dependency on Rewrite, Checker and CodeGen in shared library configuration 
Currently, all AST consumers are located in the Frontend library,
meaning that in a shared library configuration, Frontend has a
dependency on Rewrite, Checker and CodeGen.  This is suboptimal for
clients which only wish to make use of the frontend.  CodeGen in
particular introduces a large number of unwanted dependencies.

This patch breaks the dependency by moving all AST consumers with
dependencies on Rewrite, Checker and/or CodeGen to their respective
libraries.  The patch therefore introduces dependencies in the other
direction (i.e. from Rewrite, Checker and CodeGen to Frontend).

After applying this patch, Clang builds correctly using CMake and
shared libraries ("cmake -DBUILD_SHARED_LIBS=ON").

N.B. This patch includes file renames which are indicated in the
patch body.

Changes in this revision of the patch:
 - Fixed some copy-paste mistakes in the header files
 - Modified certain aspects of the coding to comply with the LLVM
   Coding Standards
