[Win] Use _mm_lfence for emitting lfence

Comment 1 karogyoker2+webkit 2018-07-30 09:45:27 PDT

This might be opened in the security category, as currently no LFENCE is emitted at all in case of a Windows build.

According to Filip Pizlo[1] emitting lfence is not needed so I think this bug can be closed as WONTFIX.

Now lfence is removed.
