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.

4722f1921a Fix bug 25362 "cppcoreguidelines-pro-bounds-array-to-pointer-decay does not consider const"
Summary:
The current matcher is
  implicitCastExpr(unless(hasParent(explicitCastExpr())))
but the AST in the bug is
  `-CXXStaticCastExpr 0x2bb64f8 <col:21, col:55> 'void *const *'
static_cast<void *const *> <NoOp>
    `-ImplicitCastExpr 0x2bb64e0 <col:47> 'void *const *' <NoOp>
      `-ImplicitCastExpr 0x2bb64c8 <col:47> 'void **'
<ArrayToPointerDecay>
        `-DeclRefExpr 0x2bb6458 <col:47> 'void *[2]' lvalue Var
0x2bb59d0 'addrlist' 'void *[2]'
i.e. an ImplicitCastExpr (const cast) between decay and explicit cast.

f33319699d [clang-tidy] Add new check cppcoreguidelines-pro-bounds-array-to-pointer-decay
Summary:
This check flags all array to pointer decays.

Pointers should not be used as arrays. array_view is a bounds-checked,
safe alternative to using pointers to access arrays.

This rule is part of the "Bounds safety" profile of the C++ Core
Guidelines, see
https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#-bounds3-no-array-to-pointer-decay
