This adds new modes to run gcmole on multiple hosts: - collect: Parse source files and store partial raw call graph in a binary output file. - merge: Read multiple partial call graphs stored by 'collect', merge them and store the gc-suspect information. - check: Use the stored suspect information to check source files for problems. The modes 'collect' and 'check' support sharding parameters, so that each shard runs on a deterministic fraction of the source files. The previous way of running gcmole locally is unchanged as 'full' run. All modes also support the --test-run parameter, running against a test double. The parameter to reuse suspects is removed as the new 'check' mode makes it redundant. This also adds python tests to verify most additions for merging call graphs and for distributing source files to shards. The new API is used on the infra side via the gcmole_v3 config, which we configure now in parallel to the previous version to test for equality. Based on the builders.pyl change, these additions also run on the v8_linux_rel trybot on this CL.
