Log:
Wrap clang module files in a Mach-O, ELF, or COFF container.
This is a necessary prerequisite for debugging with modules.
The .pcm files become containers that hold the serialized AST which allows
us to store debug information in the module file that can be shared by all
object files that were built importing the module.

rdar://problem/19104245

This reapplies r230044 with a fixed configure+make build and updated
dependencies. Take 3.

+Clang's AST files are Mach-O, ELF, or COFF containers that contain a
+``__clangast`` section which holds the AST bitstream.

 Clang's AST files are designed with a compact on-disk representation, which
 minimizes both creation time and the time required to initially load the AST
 file.  The AST file itself contains a serialized representation of Clang's
