You didn't need to do this.  The default of $(TargetPath) is correct.

You need to expand the object into its component members by clicking on 
the +.  You'll see: 
'llvm::cl::opt_storage<std::basic_string<char,std::char_traits<char>,std::allocator<char>

Can't help you here.  I have no idea why your hello.bc is corrupted.  
All I can suggest is to step through the bytecode reader and see why 
it's unhappy (there should be a reason following "bytecode didn't read 
correctly").  You might also try specifying hello.bc with a full path, 
or setting the Working Directory to where the file resides.
