- Ensure that the token stream from generated source matches the
...
original token stream in the presence of combinations of
multiline string and string interpolation. If not this will
cause mismatches when accessing code snippets, e.g when
reporting parser errors or assertions.
- Ensure that ScanAll and ScanTo are in sync when adding or
counting tokens.
- Added unit test for multiline strings and interpolation.
- Expanded GenerateSource unit test to iterate through all
loaded libraries.
- Do not report columns for compilation errors in snapshotted
code.
- Do not report columns from exceptions and errors when dealing
with snapshotted code.
- Remove length field from TokenDescriptor. It was unused.
- Remove TokenStream::ComputeTokenPosition. It was unused.

Changes to shrink the token stream representation from two words to one word.
...
On standalone dartium which has about 50000 tokens in the libraries (core, coreimpl, builtin, io etc.) this reduces the heap size by about 180kb. The size of the standalone snapshot buffer reduces by about 72kb.
Also moved the keyword symbol table to the object store so that it does not have to repopulated on every script compilation. Should benefit regular user script load times.
