  Changed paths:
    M llvm/lib/Analysis/InlineCost.cpp
    A llvm/test/Transforms/Inline/implicit-null-check.ll

  Log Message:
  -----------
  [InlineCost] Consider branches with !make.implicit metadata as free.

!make.implicit metadata attached to branch means it will very likely
be eliminated (together with associated cmp instruction).
