This patch adds support of multiple Scripted Threads in a ScriptedProcess. This is done by fetching the Scripted Threads info dictionary at every ScriptedProcess::DoUpdateThreadList and iterate over each element to create a new ScriptedThread using the object instance, if it was not already available. This patch also adds the ability to pass a pointer of a script interpreter object instance to initialize a ScriptedInterface instead of having to call the script object initializer in the ScriptedInterface constructor. This is used to instantiate the ScriptedThreadInterface from the ScriptedThread constructor, to be able to perform call on that script interpreter object instance. Finally, the patch also updates the scripted process test to check for multiple threads. rdar://84507704 Differential Revision: https://reviews.llvm.org/D117071 Signed-off-by: Med Ismail Bennani <medismail.bennani@gmail.com>
