It is impossible for bits to be 15 here so the special case is
not needed.

This function is always called with a non-negative argument, so
those special cases are not needed. In the places the argument
might be zero, the return value for a zero argument does not matter
since it would then be used to scale an array full of zeros.

actual store and load, this operation still implies a truncation
to 16 bits which the compiler will probably not realise is not
necessary here.

Writing the scaled excitation to a scratch buffer (borrowing the
'audio' array) instead of modifying it in place avoids the need
to save and restore the unscaled values.

Use saturating addition functions instead of 64-bit intermediates
and separate clipping. This is much faster when dedicated
instructions are available.
Signed-off-by: Mans Rullgard <mans@mansr.com>

Firstly, nothing in this function can overflow 32 bits so the use
of a 64-bit type is completely unnecessary. Secondly, the scale
is either a power of two or 0x7fff. Doing separate loops for these
cases avoids using multiplications. Finally, since only the number
of bits, not the actual value, of the maximum value is needed, the
bitwise or of all the values serves the purpose while being faster.
It is worth noting that even if overflow could happen, it was not
handled correctly anyway.

The operands in both cases are 16-bit so cannot overflow a 32-bit
destination. In gain_scale() the inputs are reduced to 14-bit,
so even the shift cannot overflow.

The 'shift' argument is always 1 so there is no need to pass it
explicitly in every call.

This addition must be done as 64-bit to avoid overflow and for
the subsequent clipping to be meaningful.

In 16-bit arithmetic, x * 0xffffc is simply x * -4 with extra overflows,
(and the constant was probably meant to be 0xfffc). Combined with the
shift, this simplifies to -x >> 1. Finally, clearing the low two bits
with a 32-bit mask and switching to a 32-bit type allows more efficient
code on 32-bit machines.

It expects maximum value to be 32767 but calculations in scale_vector()
which uses this function can give it ABS(-32768) which leads to wrong
result and thus clipping is needed.

Due to some mistake LPC vector for the first subframe was used for all
subframes instead of their own LPC vectors.
