As this PR mentions a lot of different FAILs, some started earlier, others later, some got fixed afterwards, others not, it is hard to find out what can/should be done. I can't reproduce the gcc.target/aarch64/sve/mask_load_slp_1.c FAILs, I get 48 / 40 instructions as expected even with r11-3822. I get 40 / 32 in r11-3823 up to r11-4480, and starting from r11-4481 again 48 / 40 until now.
