Allow creating llvm::Function in non-zero address spaces

Browse Source 
Most users won't have to worry about this as all of the
'getOrInsertFunction' functions on Module will default to the program
address space.

An overload has been added to Function::Create to abstract away the
details for most callers.

This is based on https://reviews.llvm.org/D37054 but without the changes to
make passing a Module to Function::Create() mandatory. I have also added
some more tests and fixed the LLParser to accept call instructions for
types in the program address space.
