The benchmarks use these packages. These need to be migrated and rolled into the SDK DEPS to complete the benchmark migration:

• async
• benchmark_harness
• box2d (this is "vendored" in some benchmarks)
• compiler
• convert
• crypto
• csslib
• ffi
• fixnum
• intl
• js
• meta
• pedantic
• unittest (vendored in a single benchmark, will not be migrated, benchmarks need to stop using this)
• vector_math (this is "vendored" in some benchmarks)
• vm_service
