98dc599790 dsymutil: strip unused types from imported DW_TAG_modules 
This patch teaches dsymutil to strip types from the imported
DW_TAG_module inside of an object file (not inside the PCM) if they
can be resolved to the full definition inside the PCM. This reduces
the size of the .dSYM from WebCore from webkit.org by almost 2/3.

9e7e8839b2 dsymutil/modules: Reword the warning for static libraries without module caches 
In addition to clarifying the warning message this contains a minor functional
change in that it now warns if the *immediate* parent directory in which the
missing PCM is expected to be isn't found.

This patch also includes a more comprehensive testcase.

42562c38f5 dsymutil: Also ignore the ByteSize when building the DeclContext cache for 
clang modules.

Forward decls of ObjC interfaces don't have a bytesize.

209370260d dsymutil: print a warning when there is a module hash mismatch. 
This also updates the module binaries in the test directory because
their module hash mismatched.

e5162dba49 dsymutil: Follow references to clang modules and recursively clone the 
debug info.

This does not yet resolve external type references.
