[ARM64EC] Avoid emitting unnecessary symbol references with /guard:cf. (#123235)
.gfids$y contains a list of indirect calls for Control Flow Guard. This
wasn't working properly for ARM64EC: direct calls were being treated as
indirect calls. Make sure we correctly filter out direct calls.
This improves the protection from Control Flow Guard, and also fixes a
link error when using certain functions from oldnames.lib.

[CFGuard] Add address-taken IAT tables and delay-load support
This patch adds support for creating Guard Address-Taken IAT Entry Tables (.giats$y sections) in object files, matching the behavior of MSVC. These contain lists of address-taken imported functions, which are used by the linker to create the final GIATS table.
Additionally, if any DLLs are delay-loaded, the linker must look through the .giats tables and add the respective load thunks of address-taken imports to the GFIDS table, as these are also valid call targets.

[WinCFG] Handle constant casts carefully in .gfids emission
Summary:
The general Function::hasAddressTaken has two issues that make it
inappropriate for our purposes:
1. it is sensitive to dead constant users (PR43858 / crbug.com/1019970),
leading to different codegen when debu info is enabled
2. it considers direct calls via a function cast to be address escapes
The first is fixable, but the second is not, because IPO clients rely on
this behavior. They assume this function means that all call sites are
analyzable for IPO purposes.
So, implement our own analysis, which gets closer to finding functions
that may be indirect call targets.

Add Windows Control Flow Guard checks (/guard:cf).
Summary:
A new function pass (Transforms/CFGuard/CFGuard.cpp) inserts CFGuard checks on
indirect function calls, using either the check mechanism (X86, ARM, AArch64) or
or the dispatch mechanism (X86-64). The check mechanism requires a new calling
convention for the supported targets. The dispatch mechanism adds the target as
an operand bundle, which is processed by SelectionDAG. Another pass
(CodeGen/CFGuardLongjmp.cpp) identifies and emits valid longjmp targets, as
required by /guard:cf. This feature is enabled using the `cfguard` CC1 option.

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.
