Paul Kirth 14f292d00e [llvm-readobj] Output valid JSON for GroupSections
The current implementation output the LLVM formatted heading for group
sections, which was not valid JSON. This patch provides two small
customization points that allow the heading to vary between the two
implementations, and another that allows the section members to be
output as valid JSON objects.
