1b98b73472 Refactor force-inlining macros and use EIGEN_ALWAYS_INLINE to force inlining of the integer overflow helpers, whose non-inlining caused major performance problems, see the mailing list thread 'Significant perf regression probably due to bug #363 patches' 2011-11-06 16:27:41 -05:00

16b638c159 Throw std::bad_alloc even when exceptions are disabled, by doing new int[size_t(-1)]. 
Don't throw exceptions on aligned_malloc(0) (just because malloc's retval is null doesn't mean error, if size==0).
Remove EIGEN_NO_EXCEPTIONS option, use only compiler standard defines. Either exceptions are enabled or they aren't.

(there is no known -yet- method to get cpuid, without resolving to kernel /sys interface)
