[NFC] Header cleanup

Removed some unused headers, replaced some headers with forward class declarations. Found using simple scripts like this one: clear && ack --cpp -l '#include "llvm/ADT/IndexedMap.h"' | xargs grep -L 'IndexedMap[<]' | xargs grep -n --color=auto 'IndexedMap' Patch by Eugene Kosov <[email protected]> Differential Revision: http://reviews.llvm.org/D19219 From: Mehdi Amini <[email protected]> git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@266595 91177308-0d34-0410-b5e6-96231b3b80d8
