This makes it more convenient to get a text format profile.
Add an error for printing non-text format output to a terminal for instrumentation profile.
(It cannot be portably tested. For sample profile, raw_fd_ostream is hidden deeply so it's inconvenient to add a diagnostic.)

The new option is similar to the SampleProfile dump option.
- dump raw/indexed format into text profile format
- merge the profile and output into text profile format.
Note that Value Profiling data text format is not yet designed.
That functionality will be added later.
