  Log Message:
  -----------
  [VPlan] Fix crash with EVL tail folding intrinsic with no corresponding VP (#121542)

This fixes a crash when building SPEC CPU 2017 with EVL tail folding
when widening @llvm.log10 intrinsics.

@llvm.log10 and some other intrinsics don't have a corresponding VP
intrinsic, so this fixes the crash by removing the assert and bailing
instead.
