7b05b5093e ac3dec_fixed: always use the USE_FIXED=1 variant of the AC3DecodeContext 
The AC3DecodeContext has a float (USE_FIXED=0) and an integer
(USE_FIXED=1) variant, both of which can be present in the same binary.
This is not only very confusing, but it also breaks horribly, when one
variant is used by code expecting the other.

This currently happens, because eac3dec.c is only compiled for the float
variant, but also used from ac3dec_fixed.c, which uses the integer
variant.

The result is memory corruption, leading to crashes.

So compile eac3dec.c once for each variant and adapt it, so that it
works with the integer variant.

A loss of precission and scaling bug has been fixed by the committer

157d6f0d5b mips: port optimizations to mips n64 
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.

eae13eae9d configure, mips: remove MIPS32R2, merging it with MIPSFPU 
There are no independant uses of mips32r2 instructions except for the
FPU parts. Due to the heavy use of mips32r2 specifc fpu extensions, I
am guessing the original author intended MIPSFPU to imply MIPS32R2 anyway.

Since these fpu instructions are available on mips64 (non-r2), enable them
there as well.

Also remove the last occurence of HAVE_MIPS32R2 (which is coupled to
HAVE_MIPSFPU anyway).

mips32r2 is left in the list of options form compatability so that using
--disable-mips32r2 doesn't break anything.
