Ryan Macnak 9d376de55a [vm] Remove code collection.
Code collection interacts badly with
 - warming up compiled code
 - retaining pre-compiled code
 - code coverage
 - hot reload (deopting to an old version of a function)

Martin Kustermann aa9ce0f122 Revert "[vm] Repair the resolver abstraction, take 2."
This reverts commit d79787771e.

Reason for revert:

This caused significant performance regressions on our protobuf_decode* benchmarks (probably on more benchmarks, but we don't yet have results due to some perf infra issue).

To avoid letting the regressions land for downstream users we'll revert it.

We should measure performance impact before landing this again.

Some functions have a null ic_data_array even after being compiled.

Ryan Macnak 9e1adc54a7 [vm] When loading a compilation trace, speculatively populate ICData based on the receiver's static type.
If the receiver's static type has one concrete implementation, lookup the target for that implementation and add it to the ICData's entries. For some well-known interfaces, do the same for the most common concrete implementation (e.g., int -> _Smi).

Avoids method resolution during application startup.

Rationale:
When building with "--precompile trace.txt", the current
version silently processes the file without any feedback
on misspelled names, errors, or the like. This flag adds
the ability to get some feedback.
