40% speed up in parsing the /proc/<pid>/smaps file by changing StringTokenizer. What used to take 10ms to parse now takes 6ms.
- Profiling showed that doing the additional work to work with quotes added a bit of runtime, but most users don't use the optional quotes functionality. This speed parsing up by 20% by switching to a fast-path implementation, reverting to the slower path when necessary.
- Eliminate temporary copies of tokens. This speeds up GetWorkingSetKBytes by another 20%.
BUG=40033
TEST=Existing StringTokenizerTests.
