Mike McLaughlin 79ad10cf22 Add MachO dump writer to createdump (#51150) ... * Add MachO dump writer to createdump Instead of the hacky ELF core dumps on MacOS now createdump generates true MachO dumps. Setting the COMPlus_DbgEnableElfDumpOnMacOS environment variable is no longer needed. Add special thread info memory region containing the OS thread ids missing from macho core dumps. This allows SOS to map the thread indexes to thread ids. The address (0x7fffffff00000000) of this special memory region is above the highest user address (0x0007FFFFFFFFF000) and below a kernel reserved address (0xffffff8000xxxxxx) which is kind of moot because dumps don't include any kernel regions. lldb seems just fine with this memory region. The changes include ARM64 support also, but since I don't have a M1 device I can't build/test them. I'm hoping Steve can at least review them. Add --verbose/TRACE_VERBOSE support to tone down all the macho dump generation spew.
