[LoopSimplifyCFG] Add check for missing loop preheader (#149743) ...

Closes #147869
Closes #149679

Adds a check for a missing loop preheader during analysis. This fixes a
nullptr dereference that happened whenever LoopSimplify was unable to
generate a preheader because the loop was entered by an indirectbr
instruction (as stated in the LoopSimplify.cpp doc comment).
