Frank Tang ba6db33e06 Fix unreachable code under --harmony-intl-number-format-v3 
ICU 71 added new enum value UNUM_APPROXIMATELY_SIGN_FIELD
need to map to "approximatelySign"

We also discover a spec bug in
https://github.com/tc39/proposal-intl-numberformat-v3/issues/99

All the parts of formatRangeToParts should have a source "shared" for
the case that start and end are the same or very close.

TOOLS

This directory contains debugging and investigation tools for V8.

The contents are regularly mirrored to http://v8.dev/tools.

Local Development

For local development you have to start a local webserver under http://localhost:8000:

  cd tools/;
  npm install;
  ws;

Local Symbol Server

The system-analyzer can symbolize profiles for local binaries by running a local symbol server

  cd tools/;
  ws --stack system-analyzer/lws-middleware.js lws-static cors;

Note that the local symbol server will run nm and objdump and has access to your files.
