6b547686c5 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.

0165418d9a [GC] Remove unused configuration variable
The custom root mechanism didn't actually do anything.  ShadowStackGC, the only one which used it, just removed the gcroots before they reached the normal lowering in SelectionDAG.  As a result, the state flag had no value.

4708fedcc2 [GCRoot] Remove some unneccessary complexity
The GCStrategy provides three configuration options were are largely redundant.

1) Support for conditionally lowering gcread and gcwrite to loads and stores.  This is redundant since any GC which wished to use these abstractions would lower them out of existance before the built in lowering anyways.  As such, there's no need to have the lowering being conditional.
2) Conditional initialization for allocas marked via gcroot.  Semantically, roots have to be initialized before first potential use.  Arguably, the frontend really should have responsibility for that, but the old API allowed the frontend to ignore this detail.  Only one builtin GC used the non-initializing mode.  Since no one to my knowledge actually uses the ErlangGC strategy, I decide the slight pessimization was worth the simplicity.  If that turns out to be problematic, we can always improve the insertion algorithm to detect more existing initializing stores.

e3e43d9d57 Sort the remaining #include lines in include/... and lib/....
I did this a long time ago with a janky python script, but now
clang-format has built-in support for this. I fed clang-format every
line with a #include and let it re-sort things according to the precise
LLVM rules for include ordering baked into clang-format these days.

I've reverted a number of files where the results of sorting includes
isn't healthy. Either places where we have legacy code relying on
particular include ordering (where possible, I'll fix these separately)
or where we have particular formatting around #include lines that
I didn't want to disturb in this patch.

This patch is *entirely* mechanical. If you get merge conflicts or
anything, just ignore the changes in this patch and run clang-format
over your #include lines in the files.

Sorry for any noise here, but it is important to keep these things
stable. I was seeing an increasing number of patches with irrelevant
re-ordering of #include lines because clang-format was used. This patch
at least isolates that churn, makes it easy to skip when resolving
conflicts, and gets us to a clean baseline (again).

263517d547 [GC] Consolidate all built in GCs into a single file [NFC]
Combine a bunch of small files into a single, still rather small, file.  The primary purpose of this is to get all of the static initializers into a single file so as to have a well defined order of initialization.
