record_labels returns all the possible labels for a record identified by
a pubkey, used in updating timestamp of crds values:
https://github.com/solana-labs/solana/blob/1792100e2/core/src/crds_value.rs#L560-L577https://github.com/solana-labs/solana/blob/1792100e2/core/src/crds.rs#L240-L251
The code relies on CrdsValueLabel to be limited to a small deterministic
set of possible values for a fixed pubkey. As we expand crds values to
include duplicate shreds, this limits what the duplicate proofs can be
keyed by in the table.
In addition the computation of these labels is inefficient and will
become more so as duplicate shreds and more types of crds values are
added. An alternative is to maintain an index of all crds values
associated with a pubkey.

If a node "a" receives instance-info from node "b1" it will override any
instance-info associated with "b1" pubkey in its crds table. This makes
it less likely that when "b1" receives crds values from "a" (either
through pull or push), it sees other instances of itself (because node
"a" discarded them when it received "b1" instance info).
In order for the crds table to contain all instance-info associated with
the same pubkey at the same time, we need to add the instance tokens to
the keys in the crds table (i.e. the CrdsValueLabel).
* Adds a CLI option to the validator to enable just-in-time compilation of BPF.
* Refactoring to use bpf_loader_program instead of feature_set to pass JIT flag from the validator CLI to the executor.
Gossip and other places repeatedly de-serialize vote-state stored in
vote accounts. Ideally the first de-serialization should cache the
result.
This commit adds new VoteAccount type which lazily de-serializes
VoteState from Account data and caches the result internally.
Serialize and Deserialize traits are manually implemented to match
existing code. So, despite changes to frozen_abi, this commit should be
backward compatible.

process_pull_requests acquires a write lock on crds table to update
records timestamp for each of the pull-request callers:
https://github.com/solana-labs/solana/blob/3087c9049/core/src/crds_gossip_pull.rs#L287-L300
However, pull-requests overlap a lot in callers and this function ends
up doing a lot of redundant duplicate work.
This commit obtains unique callers before acquiring an exclusive lock on
crds table.
