[OpenCL] Fix serialization of OpenCLExtensionDecls

Summary:
I recently discovered that adding the following code into `opencl-c.h` causes
failure of `test/Headers/opencl-c-header.cl`:
```
#pragma OPENCL EXTENSION cl_my_ext : begin
void cl_my_ext_foobarbaz();
#pragma OPENCL EXTENSIOn cl_my_ext : end
```

Clang crashes at the assertion is `ASTReader::getGlobalSubmoduleID()`:
```
assert(I != M.SubmoduleRemap.end() && "Invalid index into submodule index remap");
```

The root cause of the problem that to deserialize `OPENCL_EXTENSION_DECLS`
section `ASTReader` needs to deserialize a Decl contained in it. In turn,
deserializing a Decl requires information about whether this declaration is
part of a (sub)module, but this information is not read yet because it is
located further in a module file.
