[PATCH] D51926: [scan-build-py] Prevent crashes of CTU analysis by suppressing warnings

During the mapping of functions for cross-translation unit analysis, the functions' names and the containing files are collected by clang-func-mapping. Warnings are stored in the collection too, which later makes the parsing of the collection fail. Proposed solution is to suppress all warnings during the function mapping.
