  Log Message:
  -----------
  RuntimeLibcalls: Read exception model from the module flag (#223971)

Source the exception model in the RuntimeLibcallsInfo(Module)
constructor from the "exception-model" module flag via 
Module::getExceptionModel(), instead of forwarding it from TargetOptions. 
An absent flag resolves to Default and then to the triple default; an explicit "none" 
disables exceptions.

Since the model now comes from the module, drop the ExceptionModel that
RuntimeLibraryAnalysis carried and forwarded, and its argument at every
construction site.
