This patch extracts the `msg` value of the `failwithmessage` error and uses it as the stop reason if the MSVC Runtime fails while debugging. # Before ``` lldb.exe C:\Users\charleszablit\Developer\testing\uninit.exe -b -o 'r' (lldb) target create "C:\\Users\\charleszablit\\Developer\\testing\\uninit.exe" Current executable set to 'C:\Users\charleszablit\Developer\testing\uninit.exe' (x86_64).
