r221066 - Add _lzcnt_u32 and _lzcnt_u64 to lzcntintrin.h to match Intel documentation names for these intrinsics.

[Robinson, Paul]

I thought these were already defined in Intrin.h?  Except only for Windows I guess.
Still can't reach my work systems so checking it myself might have to wait until
Monday.
