Subject: [PATCH 1/2] Remove 64b specific method and create Cache from both
memory 32 and memory 64.
Add Mem64List to Obj2Yaml and Yaml2Minidump
Fix yaml2obj minidump emission where I was passing a stack variable by reference. Change CreateRegionsCache to not double evaluate Expected<T> as it was causing unchecked to flip back to true instead slotting into an optional.
Uncomment python tests"
Run C++ and Python formatters.
Revert unchanged files.
Modify test yaml to show support for multiple mem64 entries
Remove llvm related components because they were changed in a different patch
