[llvm] Cleanup header dependencies in ADT and Support
The cleanup was manual, but assisted by "include-what-you-use". It consists in
1. Removing unused forward declaration. No impact expected. 2. Removing unused headers in .cpp files. No impact expected. 3. Removing unused headers in .h files. This removes implicit dependencies and is generally considered a good thing, but this may break downstream builds. I've updated llvm, clang, lld, lldb and mlir deps, and included a list of the modification in the second part of the commit. 4. Replacing header inclusion by forward declaration. This has the same impact as 3.
Notable changes:
- llvm/Support/TargetParser.h no longer includes llvm/Support/AArch64TargetParser.h nor llvm/Support/ARMTargetParser.h - llvm/Support/TypeSize.h no longer includes llvm/Support/WithColor.h - llvm/Support/YAMLTraits.h no longer includes llvm/Support/Regex.h - llvm/ADT/SmallVector.h no longer includes llvm/Support/MemAlloc.h nor llvm/Support/ErrorHandling.h
You may need to add some of these headers in your compilation units, if needs be.
As an hint to the impact of the cleanup, running
clang++ -E -Iinclude -I../llvm/include ../llvm/lib/Support/*.cpp -std=c++14 -fno-rtti -fno-exceptions | wc -l
before: 8000919 lines after: 7917500 lines
Reduced dependencies also helps incremental rebuilds and is more ccache friendly, something not shown by the above metric :-)

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.

blockfreq: Defer to BranchProbability::scale() (again)
Change `BlockFrequency` to defer to `BranchProbability::scale()` and `BranchProbability::scaleByInverse()`.
This removes `BlockFrequency::scale()` from its API (and drops the ability to see the remainder), but the only user was the unit tests. If some code in the future needs an API that exposes the remainder, we can add something to `BranchProbability`, but I find that unlikely.

[block-freq] Add BlockFrequency::scale that returns a remainder from the division and make the private scale in BlockFrequency more performant.
This change is the first in a series of changes improving LLVM's Block Frequency propogation implementation to not lose probability mass in branchy code when propogating block frequency information from a basic block to its successors. This patch is a simple infrastructure improvement that does not actually modify the block frequency algorithm. The specific changes are:
1. Changes the division algorithm used when scaling block frequencies by branch probabilities to a short division algorithm. This gives us the remainder for free as well as provides a nice speed boost. When I benched the old routine and the new routine on a Sandy Bridge iMac with disabled turbo mode performing 8192 iterations on an array of length 32768, I saw ~600% increase in speed in mean/median performance.
2. Exposes a scale method that returns a remainder. This is important so we can ensure that when we scale a block frequency by some branch probability BP = N/D, the remainder from the division by D can be retrieved and propagated to other children to ensure no probability mass is lost (more to come on this).

Add a division operator to BlockFrequency.
Allow a BlockFrequency to be divided by a non-zero BranchProbability with saturating arithmetic. This will be used to compute the frequency of a loop header given the probability of leaving the loop.
Our long division algorithm already saturates on overflow, so that was a freebie.

BlockFrequency: Saturate at 1 instead of 0 when multiplying a frequency with a branch probability.
Zero is used by BlockFrequencyInfo as a special "don't know" value. It also causes a sink for frequencies as you can't ever get off a zero frequency with more multiplies.
This recovers a 10% regression on MultiSource/Benchmarks/7zip. A zero frequency was propagated into an inner loop causing excessive spilling.
