Initial support for the ICL compiler on windows. Requires a new
c99wrap with ICL support (1.0.2+).

Currently not much different speed wise compared to msvc. In the
future with a few changes it can be made to support the inline asm.
This would be the primary reason for using it.

Passed all fate tests, versions tested:
    13.1.1.171 (2013 Update 3) x86 and x64
    12.1.5.344 (2011 Update 11) x86 and x64

The old check would fail on huge but not infinite values
and the later code could then fail to handle them correctly in
some cases.

Change the check_exec_crash test to use a function pointer instead of
simply calling the function. The EBP availability test will crash when
compiled with ICL likely due to compiler optimization shenanigans.

Originally the check_exec_crash code was moved out of main to fix a
problem with gcc's treatment of non-leaf main on x86_32. Libav already
moved the code out of main but the addition of the function pointer will
prevent any inlining which fixes the remaining problem.

A function pointer is used since it is compiler agnostic (as opposed to
say __attribute__ ((noinline)) which would only work with gcc compatible
compilers).

This more evenly distributes the load between threads

This also fixes the chroma filtering where the filter was applied twice

  cpu: Include common.h for av_popcount64

Due the crappy issue of classes having to be unique,
we cannot even have classes with identical content,
otherwise the compiler or linker is free to merge them,
giving the same result and bugs as if we had only one class.
Besides redesigning the option code to handle this correctly
I see only the option of requiring any two classes to have
different names, but the list of requirements for
AVClasses is getting kind of unmanageable.
