1.3.2: FLAC__CPUINFO_IA32_CPUID_SSE3 undeclared
...2' undeclared (first use in this
function)
This is a result on inconsistent #if guards in src/libFLAC/cpu.c,
combined with an old compiler (GCC 4.2.1) that doesn't have
x86intrin.h.
Specifically, the definition of FLAC__CPUINFO_IA32_CPUID_SSE3 etc.
is guarded by
#if FLAC__HAS_X86INTRIN || FLAC__AVX_SUPPORTED
However, the later use in ia32_cpu_info is guarded by
#if !defined FLAC__NO_ASM && (defined FLAC__HAS_NASM || FLAC__HAS_X86INTRIN)
In our case, we have
FLAC__HAS_NASM 1
FLAC__HAS_X86INTRIN 0
FLAC__AVX_SUPPORTED 0

I thought the original problem was with `___cpuidex`, not `__cpuid`!

FLAC__SSE_OS change
First off, this code is horrible to read and work on. The recent commits
are the first of what I hope is a massive clean up of this code.
