[LoopUnroll] Add RuntimeUnrollMultiExit to loop unroll options (NFC) (#124462)
Add an extra knob to RuntimeUnrollMultiExit to let backends control
whether to allow multi-exit unrolling on a per-loop basis.
This gives backends more fine-grained control on deciding if multi-exit
unrolling is profitable for a given loop and uarch. Similar to
4226e0a0c75.

[TTI] Add SCEVExpansionBudget to loop unrolling options. (#118316)
Add an extra know to UnrollingPreferences to let backends control the
maximum budget for SCEV expansions.
This gives backends more fine-grained control on the cost of the runtime
checks for runtime unrolling.

[IR] Don't include Module.h in Analysis.h (NFC) (#97023)
Replace it with a forward declaration instead. Analysis.h is pulled in
by all passes, but not all passes need to access the module.

[SCEV] Add option to forget everything in SCEV.
Summary:
Create a method to forget everything in SCEV.
Add a cl::opt and PassManagerBuilder option to use this in LoopUnroll.
Motivation: Certain Halide applications spend a very long time compiling in forgetLoop, and prefer to forget everything and rebuild SCEV from scratch.
Sample difference in compile time reduction: 21.04 to 14.78 using current ToT release build.
Testcase showcasing this cannot be opensourced and is fairly large.
The option disabled by default, but it may be desirable to enable by
default. Evidence in favor (two difference runs on different days/ToT state):
File Before (s) After (s)
clang-9.bc 7267.91 6639.14
llvm-as.bc 194.12 194.12
llvm-dis.bc 62.50 62.50
opt.bc 1855.85 1857.53

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.

[LoopUnroll] Add check to Latch's terminator in UnrollRuntimeLoopRemainder
In this patch, I'm adding an extra check to the Latch's terminator in llvm::UnrollRuntimeLoopRemainder,
similar to how it is already done in the llvm::UnrollLoop.
The compiler would crash if this function is called with a malformed loop.
Patch by Rodrigo Caetano Rocha!
