[NFCI] Return PathSensitiveBugReport where appropriate

Some compilers have trouble converting unique_ptr<PathSensitiveBugReport> to
unique_ptr<BugReport> causing some functions to fail to compile.
Changing the return type of the functions that fail to compile does not
appear to have any issues.
I ran into this issue building with clang 3.8 on Ubuntu 16.04.
