The XCore backend does not support object emission. Several tests fail for this reason when XCore is the default target. See staging buildbot builder: clang-xcore-ubuntu-20-x64. So check for backend object emission before running the tests requiring it. Incorporate isConfigurationSupported functionality in isObjectEmissionSupported, to avoid calling them both in the same tests. Differential Revision: https://reviews.llvm.org/D98400
