Name lookup doesn't work properly with Windows targets. This is most likely due to issues with name mangling, although there is at least one set of debug info related issues as well, since some of the name lookup requests appear to be failing on types rather than symbols. Specifically, this patch XFAILS the following set of tests: TestChar1632T.py TestRdar12991846.py TestConstVariables.py TestCallCPPFunction.py TestCallStopAndContinue.py TestCallUserDefinedFunction.py TestCModules.py TestCPPThis.py TestExprs2.py TestOverloadedFunctions.py TestRvalueReferences.py And fixing the underlying issue is tracked in http://llvm.org/pr24489 llvm-svn: 245338

LLDBs current first choice of evaluating functions is using the IR interpreter,
