Fedor Sergeev 02e7f0247b [PM] pass -debug-pass-manager flag into FunctionToLoopPassAdaptor's canonicalization PM 
Summary:
New pass manager driver passes DebugPM (-debug-pass-manager) flag into
individual PassManager constructors in order to enable debug logging.
FunctionToLoopPassAdaptor has its own internal LoopCanonicalizationPM
which never gets its debug logging enabled and that means canonicalization
passes like LoopSimplify are never present in -debug-pass-manager output.

Extending FunctionToLoopPassAdaptor's constructor and
createFunctionToLoopPassAdaptor wrapper with an optional
boolean DebugLogging argument.

Passing debug-logging flags there as appropriate.

Craig Topper bf6495fbcb [LoopRotate] processLoop should return true even if it just simplified the loop latch without making any other changes 
Simplifying a loop latch changes the IR and we need to make sure the pass manager knows to invalidate analysis passes if that happened.

PR35210 discovered a case where we failed to invalidate the post dominator tree after this simplification because we no changes other than simplifying the loop latch.

Fixes PR35210.
