llvm: fix crash with llvm-11 / use real phi-nodes

sparse-llvm crashes with LLVM-11. From what I can see, it's because
LLVM-11 doesn't like anymore that an instruction is first created
unattached to a basic block (LLVMClearInsertionPosition()) and
inserted at some later step (LLVMInsertIntoBuilder()). Since the
corresponding function still exist I suppose they're working correctly
and sparse-llvm somehow misuse them. I don't know.

However, this functionality is only used to create the alloca
instructions used to simulate the phi-nodes.

So, fix this crash by using real phi instructions for the phi-nodes.
