* [NFC] Simplify inner structure of InstructionPrecedenceTrackingMax Kazantsev2018-09-061-32/+17
| | | | | | | | | | | | | | Currently it has a set KnownBlocks that marks blocks as having cached answers and a map FirstSpecialInsts that maps these blocks to first special instructions in them. The value in the map is always non-null, and for blocks that are known to have no special instructions the map does not have an instance. This patch removes KnownBlocks as obsolete. Instead, for blocks that are known to have no special instructions, we just put a nullptr value. This makes the code much easier to read. llvm-svn: 341531

* [NFC] Move OrderedInstructions and InstructionPrecedenceTracking to AnalysisMax Kazantsev2018-08-301-0/+99
These classes don't make any changes to IR and have no reason to be in Transform/Utils. This patch moves them to Analysis folder. This will allow us reusing these classes in some analyzes, like MustExecute. llvm-svn: 341015
