[JumpThreading][NFC] Rename LoadInst variables

Summary:
The JumpThreading pass has several locations where to the variable name LI
refers to a LoadInst type. This is confusing and inhibits the ability to use
LI for LoopInfo as a member of the JumpThreading class. Minor formatting
and comments were also altered to reflect this change.
