Emit innermost break, continue, and repeat conditionals without selection
merges, matching SPIR-V structured-loop rules and shadPS4's control-flow
model. Split nested construct merges that would otherwise alias an outer
merge or continue target, using the full dominance-defined construct.
Add focused regressions for early loop control, nested local and nonlocal
exits, conditional latches, illegal mixed exits, and acyclic exit tails.
The focused suite passes embedded Vulkan 1.2 validation. The real
0x6c341200 compute shader now structurizes to 61 blocks and its dumped
98,650-word module passes standalone spirv-val.
