[clang][PGO] Apply artificial DebugLoc to llvm.instrprof.increment instructions (#90717)
Prior to this change the debug-location for the `llvm.instrprof.increment` intrinsic was set to whatever the current DIBuilder's current debug location was set to. This meant that for switch-statements, a counter's location was set to the previous case's debug-location, causing confusing stepping behaviour in debuggers. This patch makes sure we attach a dummy debug-location for the increment instructions. rdar://123050737
