Describe your changes
Add ToolApplicationSupport::suppressWarnings, which takes a tool and appends an ArgumentsAdjuster that adds '-w' to the arguments. This suppresses the warnings output by clang, but still allows a tool to output its own warnings.
Testing performed
Added a unit test, and tested the functionality with an existing clangmetatool-based tool.
