Move the `LLVM_INSTALL_PACKAGE_DIR` declaration from llvm/cmake/modules

the regression in `llvm-config --cmakedir` output for installed LLVM.
Since the tools directory is processed by CMake prior to

[AVR] Only push and clear R1 in interrupts when necessary
R1 is a reserved register, but LLVM gives the APIs to know when it is

The main issue here was getting inline assembly to work. One could argue
that this is the job of Clang, but for consistency I've made sure that
R1 is always usable in inline assembly even if that means clearing it
when it might not be needed.
Information on inline assembly in AVR can be found here:

different register for the output register.
* LDDWRdYQ does not have an @earlyclobber, but the pointer register is
the fixed Y register which is reserved. The register allocator won't

[libcxx][NFC] utilises compiler builtins for unary transform type-traits
Depends on D116203

Christopher Di Bella [Wed, 10 Aug 2022 21:31:03 +0000 (21:31 +0000)]
[clang] adds unary type transformations as compiler built-ins
Adds
* `__add_lvalue_reference`
* `__add_pointer`
* `__add_rvalue_reference`
* `__decay`
* `__make_signed`
* `__make_unsigned`
* `__remove_all_extents`
* `__remove_extent`
* `__remove_const`
* `__remove_volatile`
* `__remove_cv`
* `__remove_pointer`
* `__remove_reference`
* `__remove_cvref`
These are all compiler built-in equivalents of the unary type traits
found in [[meta.trans]][1]. The compiler already has all of the
information it needs to answer these transformations, so we can skip
needing to make partial specialisations in standard library
implementations (we already do this for a lot of the query traits). This
will hopefully improve compile times, as we won't need use as much
memory in such a base part of the standard library.
