[Bug 836] Speed up PDB support

http://bugs.winehq.org/show_bug.cgi?id=836

--- Comment #14 from Eric Pouech   2009-08-22 05:04:35 ---
actually, PDB speed has improved a lot (around 90% for very large files) for
loading into dbghelp a PDB file

but still without using the PDB hashtables, for which #8 still applies

So either, we keep this bug open to remind us about the fact that we don't use
all the information stored in the PDB files, or we close it as the speed for
loading PDB file (even large ones) is now more decent
