This change is needed by ChromeOS as it introduces -fno-omit-frame-pointer flag (see code.google.com/p/chromium/issues/detail?id=477749). This causes compile error for MIPS, as some MIPS optimization blocks use maximum possible number of available registers. Also, this change contains minor GN build fix for MIPS platform regarding the pitch_filter_mips.c / pitch_filter_c.c file inclusion.
