this can result in an alignment hint on arm causing a SIGBUS. casting
the input ptr to anything aside from its type is unnecessary for memcpy
and is contrary to the intent of this function.

when targeting NEON C functions with NEON equivalents won't be used, but
will contribute to binary size. the same goes for sse2, etc., but this
change is primarily concerned with binary sizes for android arm targets.
note '-noasm' or otherwise modifying VP8GetCPUInfo will have no effect
on the use of NEON functions.
this decision can be overridden by defining WEBP_DSP_OMIT_C_CODE to 0.
