volume: Get more data from volume tests
...
This makes the volume tests run in two loops and print the minimum,
maximum and standard deviation of readings from the inner loop. This
makes it easier to reason out performance drops (i.e. algorithmic
problems vs. other system issues such as processor contention).

Fixup #include directives according to Coding Style
...
Use #include "header.h" if functionality of header.h is implemented
and #include <header.h> if functionality of header.h is used.

volume: Fix sample array size for tests
...
Somewhere in the history of the MMX tests, the number of channels was
changed from 1 to 2, but the number of samples was not increased to make
it even (multiple of the frame size).

SSE/MMX/ARM: Fix high frequency noise with unusual number of channels
...
In the assembly optimized versions of SSE, a noise could occur when the
number of channels were 3,5,6 or 7. For MMX and ARM, this could occur
when the number of channels were 3.

svolume: tweak constraints for 32 bits
...
Tweak the constraints a little so that register starved 32bit systems
can select a stack variable for the channel paramter instead of reusing one of
the registers we're using in the code.
