[lldb] Add "Trace" stop reason in Scripted Thread

medismailben · medismailben · commit 85ec3b4d108b · 2023-06-16T15:52:27.000-07:00
This patch adds support to eStopReasonTrace to Scripted Threads. This is necessary when using a Scrited Process with a Scripted Thread Plan to report a special thread stop reason to the thread plan. rdar://109425542 Differential Revision: https://reviews.llvm.org/D151043 Signed-off-by: Med Ismail Bennani <ismail@bennani.ma>
