Understanding the mips32r6 and mips64r6 ISAs in the configure script is
not enough. In order to have full support for MIPS R6 in FFmpeg we need
to be able to build it, and for that we need to make sure we don't use
incompatible assembler code which makes the build fail. Ifdefing the
offending code is sufficient to fix the problem.

Commit dfa920807494 ("mips/float_dsp: fix a bug in vector_fmul_window_mips")
fixed vector_fmul_window_mips by unrolling the loop only 4 times, but also
removed the outer C loop and replaced it with assembly branches and pointer
arithmetic. When submitting my 64-bit porting patch I missed this new
assembly which also needed porting.
This patch fixes a bus error in the fate-float-dsp test when run on 64-bit
mips.

This mainly consists of replacing all the pointer arithmatic 'addiu'
instructions with PTR_ADDIU which will handle the differences in pointer
sizes when compiled on 64 bit mips systems.
The header asmdefs.h contains the PTR_ macros which expend to the correct mips
instructions to manipulate registers containing pointers.

Loop was unrolled eight times although in heder there is assumption
that len is multiple of 4.
This is fixed, and assembly code is rewritten to be more optimal and
to simplify clobber list.
