> Math.exp(10000) produces 0 instead of positive infinity on x86 32-bit platform. The reason was for some jmp instructions, it used jge instead of jae. Also changed movdqu to movsd as it was supposed to load a 64-bit number

The regression tests for exp should be explicitly updated to cover the previously erroneous input if they do not do so already.
