This is the qMemoryRegionInfo style queries from the Unwinder where it is
trying to detect "is this pc/fp in actual memory, or have I gone off the
track". In my synthesized corefile, it may only have a couple hundred bytes of
stack memory and no code memory at all. This would halt the unwind algorithms.
We have a "file" (actually an ObjectFileJSON) which will declare there to be a
text section at a virtual address range, though, so when I can't find a
corefile memory range for a given address, I want to fall back to looking for a
Section that contains the address, and report that as a memory region.
