flac dev - Jul 2016 - [PATCH] for FLAC__cpu_info_asm_ia32

Stumbled upon https://bugzilla.mozilla.org/show_bug.cgi?id=1096651#c9 bug

Some old CPU (Cyrix) sets EDX but not ECX when executing CPUID.
One of the solutions it to clear ECX before calling cpuid, and
it can be applied to libFLAC code as well, see the patch.
