[lldb] Call FixUpPointer in WritePointerToMemory (try 2) (#153585)
In architectures where pointers may contain metadata, such as arm64e,
the metadata may need to be cleaned prior to sending this pointer to be
used in expression evaluation generated code.
This patch is a step towards allowing consumers of pointers to decide
whether they want to keep or remove metadata, as opposed to discarding
metadata at the moment pointers are created. See #150537.
This was tested running the LLDB test suite on arm64e.
(The first attempt at this patch caused a failure in
TestScriptedProcessEmptyMemoryRegion.py. This test exercises a case
where IRMemoryMap uses host memory in its allocations; pointers to such
allocations should not be fixed, which is what the original patch failed
to account for).
