these functions couldn't pass fate-h264 test neither O32 nor N64 ABI
but the earlier optimization (version 1) has too much bug in O32 ABI
i will fix the bugs in function put_h264_qpel16_hv_lowpass_mmi and
avg_h264_qpel16_hv_lowpass_mmi in the future
have you installed the lastest fedora21 for loo
please review this patch again, thank you

this is just another implement using C1 float registers, and the patch make
functions more readable.
i think using C1 registers may reduce the load of general registers.
gsldlc1 and gsldrc1 are similar to ldl and ldr only different with which
register to use.
