Use simple analysis interface to preserve analysis info maintained by other loop passes.

Right now, this interface provides hooks for only to operations, 1) clone basic block 2) delete value.

function attribute for llvm by translation to the InReg parameter attribute 
and fixes test/CFrontend/2002-07-30-SubregSetAssertion.c

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.
