[yaml2obj] Fixing opening empty yaml files. Essentially echo "" | yaml2obj crashes. This patch attempts to trim whitespace and determine if the yaml string in the file is empty or not. If the input is empty then it will not properly print out an error message and return an error code. Differential Revision: https://reviews.llvm.org/D59964 A test/tools/yaml2obj/empty.yaml M tools/yaml2obj/yaml2obj.cpp llvm-svn: 357219

[yaml2obj] - Don't crash on invalid inputs. yaml2obj might crash on invalid input when unable to parse the YAML. Recently a crash with a very similar nature was fixed for an empty files. This patch revisits the fix and does it in yaml::Input instead. It seems to be more correct way to handle such situation. With that crash for invalid inputs is also fixed now.
