Execution counts for Tier 1 instructions.
The "miss ratio" column shows the percentage of times the instruction executed that it deoptimized. When this happens, the base unspecialized instruction is not counted.

Allocations, frees and dict materializatons
Below, "allocations" means "allocations that are not from a freelist". Total allocations = "Allocations from freelist" + "Allocations".
"Inline values" is the number of values arrays inlined into objects.
The cache hit/miss numbers are for the MRO cache, split into dunder and other names.
