Increase performance by fetching only the necessary points.

1097 → 917 decicyles.

Call NEXT() only once since it got slower due to the overflow condition
introduced in 91b46145.

interp_trilinear:   1462 → 1280 decicycles
interp_tetrahedral: 1188 → 1097 decicycles

Tested on a Core2, GCC 4.8.

The old implementation was incomplete and could not have worked
This also fixes some warnings
New code is untested as i dont seem to have a sample file that uses this.

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.

For correct precision one may need to use asetnsamples.

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).
