This test code previously caused a failure in the module verifier, because SimplifyCFG created this invalid instruction, which tries to take the address of inline asm: %.sink = select i1 %1, i64 ()* asm "mov $0, #1", "=r", i64 ()* asm %"mov $0, #2", "=r" This has been fixed recently, presumably by James Molloy's patches that re-wrote and changed parts of SimplifyCFG, so this patch just adds a regression test for it.
