a2cd07d22a avcodec/ppc/h264dsp: POWER LE support in h264_idct_dc_add_internal() fix vec_lvsl bug 
We got defective video when use GCC 4.9.2 instead of GCC 4.9.1 to compile FFMEPG. And further found
that GCC 4.8 and 4.9 need patch to fix the lvsl/lvsr bug on POWER LE, and GCC 5.1 contains
the correct code since its release. The message on gcc-patches requesting approval for lvsl/lvsr
patch is at https://gcc.gnu.org/ml/gcc-patches/2014-10/msg00228.html.

The fixed code avoids using lvsl and will not depends on GCC version, also it uses less instructions on POWER LE.

This broke build, note, LOCAL_ALIGNED_16() does not work either

The later may yield incorrect code for on-stack variables.
