gcc.log from trunk as of commit 4acbb51d7f28

Our CI detected that commit e7a36e4715c7 "[PATCH] RISC-V: Support simplify
(-1-x) for vector." introduced these testsuite failures on aarch64-linux:

I confirmed that they are still present in trunk as of commit 4acbb51d7f28
"Daily bump." from today.

Tested on Ubuntu 22.04 with:

$ ~/src/gcc/configure \
    --disable-bootstrap \
    --disable-multilib \
    && make -j 60 \
    && make -C gcc check-gcc
RUNTESTFLAGS=3Dgcc.target/aarch64/sve/acle/aarch64-sve-acle-asm.exp

I'll attach gcc.log from trunk as well as from the parent of commit
e7a36e4715c7, which was the last commit where the test passed.=
