Add support for Intel/AMD's FMA extension
...
By supporting FMA extension, the number of instruction needed
for multiply accumulate to mix channels are reduced. Since,
this extension has been around since middle of 2012, more
computers have this instruction set available.

fix __cpuid() on x86
...
The previous version used memory operands that gcc (probably dependent
on optimization flags and/or version) could address relative to the
stack pointer, but pushing %ebx onto the stack changed it. Here, the
address of the regs array is put into %esi and the individual members
are written into directly.

This still leaves cache_aligned_malloc() in

free() on memory allocated with _aligned_malloc()).
So far however there seems to be no issue with default malloc

*** NEW CODING POLICY ***
...
All #include statements that include a header that is a part of a library
bundled with ardour MUST use quotes, not angle brackets.
Do this:
#include "ardour/types.h"
NOT this:
#include <ardour/types.h>
Rationale:
This is best practice in general, to ensure we include the local version
and not the system version. That quotes mean "local" (in some sense)
and angle brackets mean "system" (in some sense) is a ubiquitous
convention and IIRC right in the C spec somewhere.
More pragmatically, this is required by (my) waf (stuff) for dependencies
to work correctly. That is:
!!! FAILURE TO DO THIS CAN RESULT IN BROKEN BUILDS !!!
Failure to comply is punishable by death by torture. :)
P.S. It's not that dramatic in all cases, but this (in combination with some
GCC flags specific to the include type) is the best way I have found to be
absolutely 100% positive the local ones are being used (and we definitely
want to be absolutely 100% positive on that one).
