Remove usages of GCC __attribute__.
...
- To allow clang to compile, as it doesn't according to #58 .
- The target attributes are not needed anymore due to makefile handling
targetting now.
- The __attribute__((unused)) used for debugging. I don't know if clang
supports this attribute or not but it doesn't seem very important so
I'm removing it just in case.

strategies/avx2/dct-avx2.c:334:25: error: pasting "g_dct_16" and "[" does
not give a valid preprocessing token
- The [ is not part of the token so compilation failed on mingw GCC 4.9.1.

Move optimizations to their own compilation units according to target.
...
- This is necessary in order to compile AVX intrinsics correctly in
Visual Studio. Having everything in their own units should also make
compiling normal C code with optimizations on easier.
- For now the makefile still relies on GCC __target__ attribute for compiling
intrinsics.

Pass preprocessor defines for supported intrinsics in VS2010 explicitly.
...
- _M_IX86_FP defines whether VS should generate code using SSE or SSE2
instructions. It isn't correct to use it to check whether optional runtime
optimizations should be compiled in. It's also not defined at all in 64-bit
mode.
- So let's just keep it simple and give a list of everything that is supported
as release optimizations. It's not clear from the documentation if all of
these are really supported. It just list a bunch of intrinsics from these
that are.
