target/119010 - add reservations for integer vector compares to zen4/zen5
The following handles TI, OI and XI mode in the respective EVEX
compare reservations that do not use memory (I've not yet run into
ones with). The znver automata has separate reservations for
integer compares (but only for zen1, for zen2 and zen3 there are
no compare reservations at all), but I don't see why that should
be necessary here.

* config/i386/zn4zn5.md (znver4_sse_cmp_avx128,
znver5_sse_cmp_avx128): Handle TImode.
(znver4_sse_cmp_avx256, znver5_sse_cmp_avx256): Handle OImode.
(znver4_sse_cmp_avx512, znver5_sse_cmp_avx512): Handle XImode.
