  Changed paths:
    M llvm/lib/Transforms/Vectorize/LoopVectorize.cpp
    A llvm/test/Transforms/LoopVectorize/X86/gep-use-outside-loop.ll

  Log Message:
  -----------
  [LV] Check pointer user are in loop when checking for uniform pointers.

Widening decisions are not set for users outside the loop. Avoid
crashing by only calling isVectorizedMemAccessUse for users in the loop.

Fixes https://github.com/llvm/llvm-project/issues/102934.
