It caused building Subzero individually to fail. Instead I've added
a header which will get included when the submodule is not present
and generates an error. The LLVM dependencies were split off into a
separate project to make this work.

This reverts commit d5d886eb.

Subzero does not know the element types of vectors, so pass it as an

Unlike LLVM, Subzero does not store the type of value a pointer
references as part of the pointer's type information. So add a type
argument to createGEP(). Also add the type to createStore(), to
enable smaller types to be emulated by larger ones.

Subzero has unrelated types for constants and variables. Both are
operands to instructions, but we can't express this relationship at
the Nucleus level. We'd require a large number of Value to Operand
conversions. Instead, an Assign instruction is provided to convert
a Constant into a Value.

larger than 1 byte. Now the full pixels are copied in the
