AMR NB and WB decoders are optimized for MIPS architecture.
Appropriate Makefiles are changed accordingly.
Cnfigure script is changed in order to support optimizations.
Optimizations are enabled by default when compiling is done for
mips architecture.
Appropriate cflags are automatically set.
Support for several mips CPUs is added in configure script.
New ffmpeg options are added for disabling optimizations.
The FFMPEG option --disable-mipsfpu disables MIPS floating point
optimizations.
The FFMPEG option --disable-mips32r2 disables MIPS32R2
optimizations.
The FFMPEG option --disable-mipsdspr1 disables MIPS DSP ASE R1
optimizations.
The FFMPEG option --disable-mipsdspr2 disables MIPS DSP ASE R2
optimizations.

ff_acelp_lsp2lpc in lpc.c.

This replaces use of FRAC_BITS in the MULL() definition with a third
argument specifying the shift amount. All uses of this macro are
updated to pass FRAC_BITS as third argument.
