Fix several instances of macros being defined multiple times
in several targets. Most of these are just simple duplication in a
TargetInfo or OSTargetInfo of things already defined in
InitializePredefinedMacros or InitializeStandardPredefinedMacros,
but there are a few that aren't:
* AArch64 defines a couple of feature macros for armv8.1a that are
handled generically by getTargetDefines.
* CSKY needs to take care when CPUName and ArchName are the same.
* Many os/target combinations result in __ELF__ being defined twice.
Instead define __ELF__ just once in InitPreprocessor based on
the Triple, which already knows what the object format is based
on os and target.
These changes shouldn't change the final result of which macros are
defined, with the exception of the changes to __ELF__ where if you
explicitly specify the object type in the triple then this affects
if __ELF__ is defined, e.g. --target=i686-windows-elf results in it
being defined where it wasn't before, but this is more accurate as an
ELF file is in fact generated.

This partially reverts commit 77ac823fd285973cfb3517932c09d82e6a32f46d.
Halide uses le32/le64 (https://github.com/halide/Halide/pull/5934).
Temporarily brings back the code part to give them some time for migration.
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.

Targets.cpp is getting unwieldy, and even minor changes cause the entire thing
to cause recompilation for everyone. This patch bites the bullet and breaks
it up into a number of files.
I tended to keep function definitions in the class declaration unless it
caused additional includes to be necessary. In those cases, I pulled it
over into the .cpp file. Content is copy/paste for the most part,
besides includes/format/etc.
