// Regression test for a module-phase compile-time blow-up in deinline_opt.
//
// A multi-export module whose exports share a chain of helpers, each containing
// a deep nested `let` stack, produces many `NoInlinePreference` synthetic
// helpers.  The module-phase deinline size search iterated over that whole
// synthetic-function set, re-running full code generation per function per pass.
// In module phase the search can never keep a flip (its guard only explores the
// strictly-larger non-inline -> inline direction for these synthetics), so it is
// a guaranteed no-op, yet it still costs O(functions) superlinear code
// generations and on larger modules makes compilation appear to hang.
//
// This test simply compiles such a module and runs both exports.  Before the fix
// it does not finish in any reasonable time; after the fix it compiles quickly
// and produces the expected results.
