optimise readpdb.c filename and dirname handling, following r14158
r14158 introduced a dedup pool to store pairs (filename,dirname).
The windows debug info reader (readpdb.c) performance was still to be
improved, as calls to ML_(addFnDn) were done for each line loc to add.
With this patch, the nr of calls to ML_(addFnDn) should be reduced
Code has been compiled and regtested on linux, but no windows/wine test
