These macros are defined in avr-gcc and are useful when working with
assembly. For example, startup code needs to copy the contents of .data
from flash to RAM, but should use elpm (instead of lpm) on devices with
more than 64kB flash. Without __AVR_HAVE_ELPM__, there is no way to know
whether the elpm instruction is supported.
This partially fixes https://github.com/llvm/llvm-project/issues/56157.

This macro is defined in avr-gcc, and is very useful especially in
assembly code to check whether particular instructions are supported. It
is also the basis for other macros like __AVR_HAVE_ELPM__.

This simplifies the code by avoiding some special cases for family names
(as opposed to device names).

This symbol is defined in avr-gcc. Because AVR normally uses the ELF
format, define the symbol unconditionally.
This patch is needed to get Clang to compile compiler-rt.

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.
