When trying to debug some `compiler-rt` unittests, 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 so the unittests used a hardcoded `-O2` which often makes debugging impossible. This patch addresses this by instead using `-O0` if `COMPILER_RT_DEBUG`. Changes relative to the previous commit: - Use `string(APPEND)` for `COMPILER_RT_TEST_COMPILER_CFLAGS`. - Omit `-O3` from `COMPILER_RT_TEST_COMPILER_CFLAGS` in non-debug builds for now. - Provide `__sanitizer::integral_constant<bool, true>::value` instantiation for `sanitizer_type_traits_test.cpp` in debug builds. - Disable subtests of `tsan/tests/unit/tsan_trace_test.cpp` that deadlock in debug builds. - `XFAIL` `tsan/Linux/check_memcpy.c` in debug builds. Tested on `sparcv9-sun-solaris2.11`, `amd64-pc-solaris2.11`, and `x86_64-pc-linux-gnu`. Differential Revision: https://reviews.llvm.org/D91620
