// This test verifies that IDIV bypass optimizations is used when compiling for
// Atom processors with O2. The optimization inserts a test followed by a
// branch to bypass the slow IDIV instruction. This test verifies that global
// context types are used when comparing with those in the BypassTypeMap.
