When trying to debug some `compiler-rt` unittest, I initially had a hard time because

- even in a `Debug` build one needs to set `COMPILER_RT_DEBUG` to get debugging info for some of the code and
- even the so the unittests used a hardcoded `-O2` which often makes debugging impossible.

This patch addresses this by instead using `-O0` if `COMPILER_RT_DEBUG`.  `sanitizer_stacktrace_test.cpp` needs a definition of `BufferedStackTrace::UnwindImpl` to avoid a link failure.

Tested on `sparcv9-sun-solaris2.11`, `amd64-pc-solaris2.11`, and `x86_64-pc-linux-gnu`.
