target/119010 - missing reservations for Zen4/5 and SSE compares
There's the znver4_sse_test reservation which matches the memory-less
SSE compares but currently requires prefix_extra == 1. The old
znver automata in this case sometimes uses znver1-double instead of
znver1-direct, but it's quite a maze. The following simply drops
the prefix_extra requirement, but I have no idea what I'm doing here.
There doesn't seem to be any documentation on the scheduler relevant
attributes used, or at least I cannot find that.
PR target/119010
* config/i386/zn4zn5.md (znver4_sse_test): Drop test of
prefix_extra attribute.
