[PATCH 0/2] MR4669: Fix PDB reading.

[eric pouech (＠epo)]

Seen with PDB generated with "latest" MS compiler.

The data here is likely to be in the same form of other hash structures
we already handle.
(eg has a first vector to describe present entries, and a second one
to describe deleteid entries; we were incorrectly expecting an empty
deleted vector... so just skip for now the deleted vector in winedump
and dbghelp... this will probably end up with a more generic code
for reloading such hash structures, but after code freeze).
