Break critical edges in inline asm before code generation
An inline asm terminator defines outputs along its target edges -- a fallthrough target and labeled targets. Code generation implements this by inserting code directly into the target blocks. This approach works only if the target blocks don't have other predecessors. Establish required invariant by extending existing code that breaks critical edges before code generation.
