Custom AndAlso/OrElse expressions created directly with LightExpression factories can return null from strict compilation because the operator method is deferred. Resolve it through the existing shared operator emitter instead of rejecting the node.

Validation

The focused regression reproduces a failure or crash on master a0950432 and passes with this change. Release solution build passes with zero warnings/errors. Both Standard and LightExpression native suites run.

Runtime	TestX passed	Legacy passed
.NET 10	361	1,756
.NET 8	361	1,755
.NET Framework 4.7.2	342	1,639

Measurements

Compare master a0950432 with this commit d7616aa5. Windows ARM64, Release; .NET 8.0.28 and 10.0.9. Compilation uses prebuilt trees; invocation uses precompiled delegates and excludes expression construction/compilation. Standard and LightExpression are measured separately.

Two fresh process rounds reverse version-loading order, pin execution to one logical CPU, disable tiered compilation, warm both versions, and alternate measurement order. Values below are medians across 14 samples per side (seven per round; 30 ms calibration target).

Measured compilation and invocation allocations match master on every control. Control delegate IL matches master.

Identical-master control runs also varied: compilation -15.2% to +23.4%, invocation -21.5% to +8.9%. Timings below are observations, not a speedup or universal performance-neutrality claim. Cases that fail or produce invalid IL on master have no meaningful before/after invocation ratio; the table uses executable controls that return the expected result in both versions. Framework correctness is tested above; its performance is not measured here.

All table pairs are master → this change. B/op is allocated bytes per operation.
