IDA 8.4.240320 (8.4sp1)

This Service Pack of IDA 8.4 is primarily a bugfix release.

Improvements:​

• + PC: improve AVX-512 instructions support (BF16, BITALG, FP16, GFNI, VBMI2, VNNI, VP2INTERSECT, VPCLMULQDQ)
• + TEAMS: don't match types from LOCAL and REMOTE databases by ordinal if they're not present in BASE
• + UI: renamed 'Copy struct type' action to 'Duplicate struct type' to better represent its behavior
