This implements a PDBASTParser and corresponding logic in
SymbolFilePDB to do type lookup by name. This is just a first
pass and leaves many aspects of type lookup unimplemented, and
just focuses on laying the framework. With this patch, you should
be able to lookup basic types by name from a PDB.
Full class definitions are not completed yet, we will instead
just return a forward declaration of the class.

PDB is Microsoft's debug information format, and although we
cannot yet generate it, we still must be able to consume it.
Reason for this is that debug information for system libraries
(e.g. kernel32, C Runtime Library, etc) only have debug info
in PDB format, so in order to be able to support debugging
of system code, we must support it.
Currently this code should compile on every platform, but on
non-Windows platforms the PDB plugin will return 0 capabilities,
meaning that for now PDB is only supported on Windows. This
may change in the future, but the API is designed in such a way
that this will require few (if any) changes on the LLDB side.
In the future we can just flip a switch and everything will
work.
This patch only adds support for line tables. It does not return
information about functions, types, global variables, or anything
else. This functionality will be added in a followup patch.
