[Bug rtl-optimization/25505] [4.0/4.1/4.2 Regression] gcc uses way too much stack space for this code

Re: comment #5:

That is a similar testcase, but not an identical one.  A better one would be
something like:

void foo() {
  if (...) {
     std::pair<int, int> = ..
     ...
  }
  if (...) {
     std::pair<int, int> = ..
     ...
  }
  if (...) {
     std::pair<int, int> = ..
     ...
  }
}

Further, a huge amount of the wastage appears to be coming from C++
temporaries, not explicit variable definitions.
