VStudio compiler errors and placing Function*->ExFunc map under ManagedStatic control.
...
This commit fixes two things. One is a pair of VStudio compiler errors stemming from variables
which defined within the for loop statement and also within the body of the for loop. I fixed these
by renaming one of the two variables. Additionally, I've made the Function*->ExFunc map in
ExternalFunctions.cpp a ManagedStatic object, so that cleanup will be done on llvm_shutdown. In repeated
uses of the interpreter, where the same Function* address may get used for completely differnet functions,
this was causing a crash.
