  Changed paths:
    M llvm/lib/Transforms/Scalar/SROA.cpp
    A llvm/test/Transforms/SROA/dbg-inline.ll

  Log Message:
  -----------
  Teach SROA to handle allocas with more than one dbg.declare.

It is technically legal for optimizations to create an alloca that is
used by more than one dbg.declare, if one or both of them are inlined
instances of aliasing variables.
