There it is! I was looking for an equivalent to Instruction::insertBefore inside
BasicBlock. (Something along the lines of BasicBlock::appendInstruction.)

AddGlobalMapping seems like a better way to go.
> The IRBuilder class is more than just a factory; it's actually
designed to write instructions sequentially into the current block. However, if
you don't give it an insertion point, it will just create the instructions
as orphans, and you can land them in basic blocks with the APIs that Eli
mentioned.

At first it scared me a little, but the more I think about it, the more it
becomes obvious that the order in which instructions are generated should be
about the same as the order in which they're executed.
Thanks for your help!
