New Revision: 32af48cdcf182163e780fff14a89fdb4716dcb4b

URL: https://github.com/llvm/llvm-project/commit/32af48cdcf182163e780fff14a89fdb4716dcb4b
DIFF: https://github.com/llvm/llvm-project/commit/32af48cdcf182163e780fff14a89fdb4716dcb4b.diff

LOG: [IVDescriptors] Clean up includes.

Some includes are not required and forward declarations can be used
instead. This also exposed a few places that were not directly including
required files.

Added: 
    

Modified: 
    llvm/include/llvm/Analysis/IVDescriptors.h
    llvm/lib/Transforms/Scalar/LICM.cpp
    llvm/lib/Transforms/Scalar/LoopIdiomRecognize.cpp
    llvm/lib/Transforms/Scalar/LoopUnswitch.cpp

Removed:
