Gadi Haber 55d27cdd65 [X86][Haswell]: Updating the scheduling information for the Haswell subtarget.
Updated the scheduling information for the Haswell subtarget with the following changes:

Regrouped the instructions after adding appropriate load + store latencies.
Added scheduling for missing instructions such as the GATHER instrs.
The changes were made after revisiting the latencies impact of all memory uOps.
