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

; Verify that we accept calls to variables in the program AS:
; RUN: llvm-as -data-layout "P40" %s -o - | llvm-dis - | FileCheck %s
; CHECK: target datalayout = "P40"
; We should get a sensible error for a non-program address call:
; RUN: not llvm-as -data-layout "P39" %s -o /dev/null 2>&1 | FileCheck %s -check-prefix ERR-AS39
; ERR-AS39: error: '%fnptr' defined with type 'void (i16) addrspace(40)*' but expected 'void (i16) addrspace(39)*'
; And also if we don't set a custom program address space:
; RUN: not llvm-as %s -o /dev/null 2>&1 | FileCheck %s -check-prefix ERR-AS0
; ERR-AS0: error: '%fnptr' defined with type 'void (i16) addrspace(40)*' but expected 'void (i16)*'
