lib: add ASCII fast path to getStringWidth()

2019-09-03T04:02:34+00:00

A lot of strings that are going to be passed to `getStringWidth()`
are ASCII strings, for which the calculation is rather easy and
calling into C++ can be skipped.

benchmark: use test/common/tmpdir consistently

2019-08-11T02:21:35+00:00

Many benchmarks use test/common/tmpdir. This changes 3 benchmarks that
use NODE_TMPDIR to also use test/common/tmpdir.

This is necessary in preparation for the next commit that changes tmpdir
to delete tmpdir.path when the Node.js process exits. Thus, if multiple
benchmarks are run sequentially, the ones that use tmpdir will remove
the directory and the ones changed here would fail because it does not
exist. This happens when running test/benchmark.

Note: to explicitly select a directory for tmpdir, use NODE_TEST_DIR.
