  [DWARF] Identify prologue_end by instruction rather than DILocation (#107264)

Currently, we identify the end of the prologue as being "the instruction
that first has *this* DebugLoc". It works well enough, but I feel
identifying a position in a function is best communicated by a
MachineInstr. Plus, I've got some patches coming that depend upon this.
