This patch introduces a new way to load modules programatically with Scripted Processes. To do so, the scripted process blueprint holds a list of dictionary describing the modules to load, which their path or uuid, load address and eventually a slide offset. LLDB will fetch that list after launching the ScriptedProcess, and iterate over each entry to create the module that will be loaded in the Scripted Process' target. The patch also refactors the StackCoreScriptedProcess test to stop inside the `libbaz` module and make sure it's loaded correctly and that we can fetch some variables from it. rdar://74520238 Differential Revision: https://reviews.llvm.org/D120969 Signed-off-by: Med Ismail Bennani <medismail.bennani@gmail.com>
