No throughput/latency information for vbroadcast

[IgorBaratta]

I noticed that there's no throughput or latency information for the vbroadcastsd instruction for zmm in the OSACA database. This can be crucial for accurate performance analysis of an outer product kernel.

Can this be added or updated in a future version?

Hi @IgorBaratta,

I added them in commit 2331e4d for Ice Lake and Skylake and they will be available in pip/godbolt with the next release

[IgorBaratta]

Thanks @JanLJL !
