While attempting to build a branch of the Linux Kernel for arm64 (repo is
git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux, branch mte-v4) with
a master GCC, I ran into the following ICE:

-----------

modified in local context

Please include the complete backtrace with any bug report.
See <https://gcc.gnu.org/bugs/> for instructions.

-----------

The compiler was built with the default configure for aarch64-linux-gnu and I
enabled only the C and C++ languages.

Attached is the preprocessed file, and here's the command line that will
trigger the ICE.

gcc -nostdinc -mlittle-endian -DKASAN_SHADOW_SCALE_SHIFT=3 -Wall -Wundef
