After Clang 6.0, changing the value of a single string can change the
order of symbols in the .rodata section. This confuses Golem's
checks for the equivalence of two binaries.
This change adds a GN flag to omit the git hash and commit time from
the Dart VM's version string to avoid re-running Golem benchmarks on
commits where the only VM change is in the version string.
To use it, pass --gn-args="dart_version_git_info=false" to gn.py
