RFR (M): 8139575: Update for x86 log in the math lib

[Deshpande, Vivek R]

Hi all

I would like to contribute a patch which optimizes Math.log() for 64 and 32 bit X86 architecture using Intel LIBM  implementation.
The improvement gives 1.9x gain over base.
Could you please review and sponsor this patch.

Thanks and regards,
Vivek
