a583990ec8 This resolves a regression of BasicAA which failed to find any memory information for overloaded intrinsics (PR1600). This resolves that issue, and improves the matching scheme to use a BitVector rather than a binary search.

static const int, which defauts PassID based pass identification.

4. [U]Long  -> Int64.

   identifying the signedness information from other sources.

issues when they see them. All changes pass DejaGnu tests and Olden.
