with black.
If you run into any problems, post to discourse about it and

This patch addresses the last remaining problems reported in PR51008.
Previous fixes for PR51008 worked under the wrong assumption that code regions
are always named (except maybe for the default region, which was automatically
named "main").
In reality, it is quite common for users to declare multiple anonymous regions.
So we cannot really use the region name as the key string of a JSON object. In
practice, code region names are completely optional.
Using "main" for the default region was also problematic because there can be
another region with that same name.
This patch fixes these issues by introducing a json::array of regions. Each
region has a "Name" field, which would default to the empty string for anonymous
regions.
Added a few more tests to verify that the JSON file format is still valid, and
that multiple anonymous regions all appear in the final output.
This patch renames object "Resources" to "TargetInfo".
Moved the getJSONTargetInfo method from class InstructionView to the
PipelinePrinter.
Removed uses of std::stringstream.
Removed unused method View::printViewJSON().
Instead of printing each region individually when using JSON format,
this patch creates a JSON object which is updated with the values of
each region, printing them at the end. New test is added for JSON output
with multiple regions.

output a valid JSON. Removed "not implemented" keys.
