This file provides __aeabi_memclr8 builtin which the Ubuntu 22.04
version of clang 14 needs to compile. Add it to prevent this oddity from
failing the build.

Add missing aeabi_memcpy.S file from llvm compiler-rt library [1]. This
is required for Aarch32 builds with clang.

Imported from the LLVM compiler_rt library on master branch as of
30 Oct 2018 (SVN revision: r345645).
This is to get the __popcountsi2(si_int a) and __popcountdi2(di_int a)
builtin which are required by a driver that uses a __builtin_popcount().

Import aeabi_ldivmod.S with divmoddi4.c and divdi3.c from the
LLVM compiler_rt library on master branch as of 30 Oct 2018
(SVN revision: r345645).
This is to get the __aeabi_ldivmod builtin, which is required
by a patch using signed long long division.

Imported from the LLVM compiler_rt library on master branch as of
30 Oct 2018 (SVN revision: r345645).
This is to get the __aeabi_llsr() builtin, which is required by a
subsequent patch that uses a logical right shift operator in AArch32.

When using __builtin_ctzll() in AArch32 code, the compiler may translate
that into a call to the __ctzdi2() function. In this case, the linking
phase fails because TF doesn't provide an implementation for it.
This patch imports the implementation of the __ctzdi2() function from
LLVM's compiler-rt project and hooks it into TF's build system. The
ctzdi2.c file is an unmodified copy from the master branch as of
July 19 2017 (SVN revision: 308480).

This patch enables compiler-rt for the AArch32 target. The code is
not used for AArch64 as the architecture supports the 64-bit division
and modulo operations natively.
