// Loop-body locals reuse one stack slot per frame: a body-declared local
// (and every compiler temp) must not grow the stack per iteration, so
// million-iteration loops run in constant stack. Covers body locals,
// nested loops (the inner loop's hidden index slot), and element reads.
// Regression (issue 0109): allocas were emitted at their use site, so each
// iteration re-executed them — LLVM only reclaims allocas at `ret`, and
// these loops segfaulted on stack exhaustion.
