  1. Add CoreCLR EH personality 

    Processing happens in two stages (as for other WinEH personalities):
 - FunctionLoweringInfo::set computes the parent relation on handler
   actions.  ClrEHFuncInfo is added to MachineModuleInfo to facilitate
   this.
 - WinException::endFunction reports funclet begin/end offsets in .xdata
   after unwind info, and reports EH clauses after the final funclet's
   unwind info.

Note: this is a provisional change to facilitate exploring exception
handling in LLILC, and will need to be reworked when LLVM's EH
representation is changed for Windows-style targets  -- see
