[PATCH] D23048: PDB: Mark extended file pages as free by default.

[Rui Ueyama via llvm-commits]

ruiu created this revision.
ruiu added a reviewer: zturner.
ruiu added a subscriber: llvm-commits.

BitVector::extend initializes extended bits as true by default.
That is not desirable because new pages should be initially free.
