perf tools: Add doc about how to build perf with Asan and UBSan
AddressSanitizer (or ASan) and UndefinedBehaviorSanitizer (or UBSan) are
very useful tools to detect program bugs:
- AddressSanitizer (or ASan) is a GCC feature that detects memory
corruption bugs such as buffer overflows and memory leaks.
- UndefinedBehaviorSanitizer (or UBSan) is a fast undefined behavior
detector supported by GCC. UBSan detects undefined behaviors of programs
at runtime.
This patch adds a document about how to use them on perf. Later patches will fix
some of the issues disclosed by them.
