Andrea Di Biagio 8e9af64da6 [X86][BtVer2] Add a read-advance to every implicit register use of CMPXCHG8B/16B. 
This is a follow up of r369642.

This patch assigns a ReadAfterLd to every implicit register use of instruction
CMPXCHG8B and instruction CMPXCHG16B. Perf micro-benchmarks show that implicit
registers are read after 3cy from the start of execution.
