Chandler Carruth 2946cd7010 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.

Evandro Menezes ea9d90083f [AArch64] Simplify the scheduling predicates (NFC)
The instruction encodings make it unnecessary to distinguish extended W-form
from X-form instructions.

Evandro Menezes 6fe51ac973 [AArch64] Fix Exynos predicates (NFC)
Fix the logic in the definition of the `ExynosShiftExPred` as a more
specific version of `ExynosShiftPred`.  But, since `ExynosShiftExPred` is
not used yet, this change has NFC.

Evandro Menezes 53f0d41dc4 [AArch64] Refactor the Exynos scheduling predicates

case, for the Exynos processors.
