Make dependency between certain analysis passes transitive (reapply)
LazyBlockFrequenceInfoPass, LazyBranchProbabilityInfoPass and LoopAccessLegacyAnalysis all cache pointers to their nestled required analysis passes. One need to use addRequiredTransitive to describe that the nestled passes can't be freed until those analysis passes no longer are used themselves.
There is still a bit of a mess considering the getLazyBPIAnalysisUsage and getLazyBFIAnalysisUsage functions. Those functions are used from both Transform, CodeGen and Analysis passes. I figure it is OK to use addRequiredTransitive also when being used from Transform and CodeGen passes. On the other hand, I figure we must do it when used from other Analysis passes. So using addRequiredTransitive should be more correct here. An alternative solution would be to add a bool option in those functions to let the user tell if it is a analysis pass or not. Since those lazy passes will be obsolete when new PM has conquered the world I figure we can leave it like this right now.
Intention with the patch is to fix PR49950. It at least solves the problem for the reproducer in PR49950. However, that reproducer need five passes in a specific order, so there are lots of various "solutions" that could avoid the crash without actually fixing the root cause.
This is a reapply of commit 3655f0757f2b4b, that was reverted in 33ff3c20498ef5c2057 due to problems with assertions in the polly lit tests. That problem is supposed to be solved by also adjusting ScopPass to explicitly preserve LazyBlockFrequencyInfo and LazyBranchProbabilityInfo (it already preserved OptimizationRemarkEmitter which depends on those lazy passes).

Revert "Make dependency between certain analysis passes transitive"
This reverts commit 3655f0757f2b4b61419446b326410118658826ba.
It caused assertion failures related to setLastUser in polly builds.

Sink all InitializePasses.h includes
This file lists every pass in LLVM, and is included by Pass.h, which is very popular. Every time we add, remove, or rename a pass in LLVM, it caused lots of recompilation.
I found this fact by looking at this table, which is sorted by the number of times a file was changed over the last 100,000 git commits multiplied by the number of object files that depend on it in the current checkout: recompiles touches affected_files header 342380 95 3604 llvm/include/llvm/ADT/STLExtras.h 314730 234 1345 llvm/include/llvm/InitializePasses.h 307036 118 2602 llvm/include/llvm/ADT/APInt.h 213049 59 3611 llvm/include/llvm/Support/MathExtras.h 170422 47 3626 llvm/include/llvm/Support/Compiler.h 162225 45 3605 llvm/include/llvm/ADT/Optional.h 158319 63 2513 llvm/include/llvm/ADT/Triple.h 140322 39 3598 llvm/include/llvm/ADT/StringRef.h 137647 59 2333 llvm/include/llvm/Support/Error.h 131619 73 1803 llvm/include/llvm/Support/FileSystem.h
Before this change, touching InitializePasses.h would cause 1345 files to recompile. After this change, touching it only causes 550 compiles in an incremental rebuild.

Update the file headers across all of the LLVM projects in the monorepo to reflect the new license.
We understand that people may be surprised that we're moving the header entirely to discuss the new license. We checked this carefully with the Foundation's lawyer and we believe this is the correct approach.
Essentially, all code in the project is now made available by the LLVM project under our new license, so you will see that the license headers include that license only. Some of our contributors have contributed code under our old license, and accordingly, we have retained a copy of our old license notice in the top-level files in each project and repository.

Require DominatorTree when requiring/preserving LoopInfo in the old pass manager
Summary: Require DominatorTree when requiring/preserving LoopInfo in the old pass manager
BreakCriticalEdges tries to keep LoopInfo and DominatorTree updated if they exist. However, since commit r321653 and r321805, to update LoopInfo we must have a DominatorTree, or we will hit an assert.
To fix this we now make a couple of passes that only required/preserved LoopInfo also require DominatorTree.
This solves PR37334.

[BPI] Add new LazyBPI analysis
Summary: The motivation is the same as in D22141: In order to add the hotness attribute to optimization remarks we need BFI to be available in all passes that emit optimization remarks. BFI depends on BPI so unless we make this lazy as well we would still compute BPI unconditionally.
The solution is to use the new LazyBPI pass in LazyBFI and only compute BPI when computation of BFI is requested by the client.
I extended the laziness test using a LoopDistribute test to also cover BPI.

[BFI] Add new LazyBFI analysis pass
Summary: This is necessary for D21771. In order to add the hotness attribute to optimization remarks we need BFI to be available in all passes that emit optimization remarks.
However we don't want to pay for computing BFI unless the hotness attribute is requested.
This is achieved by making BFI lazy at the very high-level through a new analysis pass -- BFI is not calculated unless requested.
I am adding a test to check the laziness under D21771 where the first user of the analysis is added.
