Also making use of alloc_trim_analysis() again because the effect of
inter-channel correlation on the bitstream is really in terms of absolute
number of bits/samples.

The idea here is that it's better to fold a higher band -- even if it was
coded less accurately -- than a lower band that may have a different
temporal structure.

Also fixed a fixed-point breakage.

Previous limit was effectively 120.

Both ended up causing more harm than good (e.g. violating energy conservation)
and provided little benefit. This also saves ~3 kB code size on x86-86.

I've been compiling CELT for 64-bit Windows and it all seems to work
fine (with the occasional benign warning message) except for one place,
and that is in "float_cast.h" where there is some inline assembly
language that gets complied for Windows. Since the Microsoft 64-bit
compiler won't allow inline assembly language (and *still* doesn't have
"lrintf").

Still need to make it use the right channel in stereo.

Uses a scaling factor that gets applied to the allocation matrix.
