This patch adds support for saving minidumps with the arm64
architecture. It also will cause unsupported architectures to emit an
error where before this patch it would emit a minidump with partial
information. This new code is tested by the arm64 windows buildbot that
was failing:
https://lab.llvm.org/buildbot/#/builders/219/builds/6868
This is needed following this PR:
https://github.com/llvm/llvm-project/pull/71772
Prior to this patch, each core file plugin (ObjectFileMachO.cpp and
ObjectFileMinindump.cpp) would calculate the address ranges to save in
different ways. This patch adds a new function to Process.h/.cpp:
```
Status Process::CalculateCoreFileSaveRanges(lldb::SaveCoreStyle core_style, CoreFileMemoryRanges &ranges);
```
The patch updates the ObjectFileMachO::SaveCore(...) and
ObjectFileMinindump::SaveCore(...) to use same code. This will allow
core files to be consistent with the lldb::SaveCoreStyle across
different core file creators and will allow us to add new core file
saving features that do more complex things in future patches.
This change adds save-core functionality into the ObjectFileELF that enables
saving minidump of a stopped process. This change is mainly targeting Linux
running on x86_64 machines. Minidump should contain basic information needed
to examine state of threads, local variables and stack traces. Full support
for other platforms is not so far implemented. API tests are using LLDB's
MinidumpParser.
This relands commit aafa05e, reverted in 1f986f6.
Failed tests were fixed.
