[vm/compiler] Fix DelayAllocations pass

When looking at a phi use of an allocation, we must consider *all*
inputs that refer to this allocation and not just the first one.

Otherwise, we might end up sinking allocation down to a use that does
not dominate all uses of the allocation.

Fixes https://github.com/flutter/flutter/issues/98466
