OK, the attached patch adds FLAC__SSE*_SUPPORTED and also moves their
definitions to cpu.h.
It also adds GCC 4.9 support (http://gcc.gnu.org/gcc-4.9/changes.html:
"It is now possible to call x86 intrinsics from select functions in a file
that are tagged with the corresponding target attribute without having
to compile the entire file with the -mxxx option")

I also found that I wrote "#ifdef _MSC_VER" instead of
"#if defined _MSC_VER || defined __INTEL_COMPILER". The second attached patch
fixes this.
