When -fPIE is enabled (by default), nonlocal_goto tests fail because
ira drops reg equivalences for function invariants such as stack
addresses, and then, instead of the expected add instructions, we get
ldr to restore the pseudo holding the address, as it ends up living in
a stack slot across a call.
Tested o aarch64-linux-gnu with --enable-default-pie. Ok to install?
for gcc/testsuite/ChangeLog
* gcc.target/aarch64/sme/nonlocal_goto_1.c: Accept ldr.
* gcc.target/aarch64/sme/nonlocal_goto_2.c: Likewise.
* gcc.target/aarch64/sme/nonlocal_goto_3.c: Likewise.

More tolerance and less prejudice are key for inclusion and diversity.
Excluding neuro-others for not behaving ""normal"" is *not* inclusive!
