[X86][Sched] Add InstRW for CLC on Intel after SNB. 

Summary:
After SNB, Intel CPUs can rename CF independently of other EFLAGS,
so the renamer can zero it for free. Note that STC still consumes resources.

To reproduce: `$ llvm-exegesis -mode=uops -opcode-name=CLC`

On SNB:
```
---
key:
  opcode_name:     CLC
  mode:            uops
  config:          ''
cpu_name:        sandybridge
llvm_triple:     x86_64-unknown-linux-gnu
num_repetitions: 10000
measurements:
  - { key: '3', value: 0.0014, debug_string: SBPort0 }
  - { key: '4', value: 0.0013, debug_string: SBPort1 }
  - { key: '5', value: 0.0003, debug_string: SBPort4 }
  - { key: '6', value: 0.0029, debug_string: SBPort5 }
  - { key: '10', value: 0.0003, debug_string: SBPort23 }
error:           ''
info:            'instruction is serial, repeating a random one.
Snippet:
CLC
'
...
```

On HSW:
```
---
key:
  opcode_name:     CLC
  mode:            uops
  config:          ''
cpu_name:        haswell
llvm_triple:     x86_64-unknown-linux-gnu
num_repetitions: 10000

  - { key: '3', value: 0.001, debug_string: HWPort0 }
  - { key: '4', value: 0.0009, debug_string: HWPort1 }
  - { key: '5', value: 0.0004, debug_string: HWPort2 }

  - { key: '9', value: 0.0022, debug_string: HWPort6 }
  - { key: '10', value: 0.0001, debug_string: HWPort7 }
