Shubham Sandeep Rastogi 775258d758 Add support for salvaging debug info from icmp instrcuctions. ...

salvageDebugInfo is a function that allows us to reatin debug info for
instructions that have been optimized out. Currently, it doesn't support
salvaging the debug information from icmp instrcutions, but DWARF
expressions can emulate an icmp by using the DWARF conditional
expressions. This patch adds support for salvaging debug information
from icmp instructions.
