Etienne Bergeron 3ac879f9a6 Add missing decoding patterns toRoundUpToInstrBoundary 
Summary:
The RoundUpToInstrBoundary determines intructions boundary and it's used to determine how to patch (intercept) functions.

The current x64-bit implementation is incomplete. This patch is adding patterns observed when trying to sanitize a 64-bit executable on my computer.

Thw two current functions not intercepted are:
```
RaiseExceptionStub:
000000007720C3B0 EB 06                jmp         RaiseException (07720C3B8h)
