that can lead to security vulnerabilities Also, fix a few places that were causing -Wshadow and -Wformat-nonliteral warnings to be emitted. This reapplies the patch that was reverted in caaafe4ae250 because it broke Fuchsia builders. I reverted the changes I made to InstrProfData.inc and instead renamed the variables in InstrProfilingWriter.c. Also fixed a bug in function add_security_warnings that was causing it to pass -Wformat-nonliteral when the compiler doesn't support it.
