[Compiler-RT] On Apple Platforms switch to always emitting full debug info
Previously the build used `-gline-tables-only` when `COMPILER_RT_DEBUG`
was off (default) and `-g` when `COMPILER_RT_DEBUG` was on. The end
result of this meant that the release build of the Sanitizer runtimes
were difficult to debug (e.g. information about variables and function
arguments were missing).
Presumably the reason for preferring `-gline-tables-only` for release
builds was to save space. However, for Apple platforms this doesn't
matter because debug info lives in separate `.dSYM` files (which aren't
shipped) rather than in the shipped `.dylib` files.
Now on Apple platforms we always emit full debug info if the compiler
supports it and we emit a fatal error if `-g` isn't supported.
