A previous commit enabled LLDB to be able to debug a program launched via ld: https://reviews.llvm.org/D108061.

This commit adds the ability to debug a program launched via ld when it happens during an exec into the dynamic loader. There was an issue where after the exec we would locate the rendezvous structure right away but it didn't contain any valid values and we would try to set the dyanamic loader breakpoint at address zero. This patch fixes that and adds a test.

When a callee function is inlined via an invoke instruction, every function call inside the callee, if not an invoke,  will be converted to an invoke after cloned to the caller body. I found that during the conversion the !prof metadata was dropped. This in turned caused a cloned indirect call not properly promoted in subsequent passes.

The particular scenario I was investigating was with AutoFDO and thinLTO. In prelink, no ICP was triggered (neither by the sample loader nor PGO ICP), no indirect call was promoted. This is because 1) the particular indirect call did not have inlined samples;  and 2) PGO ICP was intentionally disabled.  After inlining, the prof metadata was dropped. Then in postlink, PGO ICP jumped in but didn't do anything. Thus the opportunity was missed.

I'm making a simple fix to preserve !prof metadata when converting call to invoke.

There are a couple of issues with the python bindings on Windows:
- `create_symlink` requires special permissions on Windows - using `copy_if_different` instead allows the build to complete and then be usable
- the path to the `python_executable` is likely to contain spaces if python is installed in Program Files. llvm's python substitution adds extra quotes in order to account for this case, but mlir's own python substitution does not
- the location of the shared libraries is different on windows
- if the type is not specified for numpy arrays, they appear to be treated as strings

I've implemented the smallest possible changes for each of these in the patch, but I would actually prefer a slightly more comprehensive fix for the python_executable and the shared libraries.

For the python substitution, I think it makes sense to leverage the existing %python instead of adding %PYTHON and instead add a new variable for the case when preloading is needed. This would also make it clearer which tests are which and should be skipped on platforms where the preloading won't work.

For the shared libraries, I think it would make sense to pass the correct path and extension (possibly even the names) to the python script since these are known by lit and don't have to be hardcoded in the test at all.
