Types that came from a Clang module are nested in DW_TAG_module tags in DWARF.
This patch recreates the Clang module hierarchy in LLDB and sets the owning
module information accordingly. My primary motivation is to facilitate looking
up per-module APINotes for individual declarations, but this likely also has
other applications.
The fact that Clang modules are orthogonal to DeclContexts made the
implementation in LLDB challenging. In the end I extended
`lldb_private::CompilerDeclContext` to hold a pair of `clang::DeclContext *`
and `clang::Module *` and made sure to use CompilerDeclContext everywhere in
TypeSystemClang. To save memory for all non-Clang typesystems, the extra data
for the owning module ID is hidden in the CompilerDeclContext's opaque pointer:
If it isn't a raw clang::DeclContext pointer, it is an index into an array of
Module ID + DeclContexts.
