'inSubLoop' & ' pointerInvalidatedByLoop' was member function of 'LICM'
These are defined in class itself. Its required to move these out of LICM class
Because these has usage in exposed utility & dependent routines (i.e. SinkRegion).
For now these are kept in same file, but later I'm planning to move these to 
other utility file(i.e. LICMCore.cpp)

Regards,
Ashutosh

Hi,

The approach looks good. Aside from Hal's suggestions, only a few comments.

Please don't repeat the function/method in the comments. Use "\brief" instead. Also fix this issue in other places of the patch too.
