llvmGen: Ensure that entry labels don't have predecessors
The LLVM IR forbids the entry label of a procedure from having any
predecessors. In the case of a simple looping function the LLVM code
generator broke this invariant, as noted in #17589. Fix this by
moving the function prologue to its own basic block, as suggested by
@kavon in #11649.
Fixes #11649 and #17589.
