*	[GlobalISel] Narrow scalar selects	Richard-Qin-X	2026-08-15	1	-0/+2
\| \| \| \|	Match LLVM's narrowScalarSelect lowering for wide scalar values. Build widened sources from LLT destinations so CSE hits reuse the actual result register instead of introducing copies.

\| \| \| \|	Implement the single LLVM-compatible MIR document path with structured\nembedded-IR references, YAML mappings, constants, and deterministic printing.\n\nKeep pointer LLT widths DataLayout-derived, reject layout-dependent output\nwhen embedded IR is omitted, and record the fixed-baseline compatibility\ncontract and regression coverage.

\| \| \| \|	Model ordered function-local metadata tuples with explicit embedded-IR and MachineFunction reference scopes. Preserve slot zero, distinct nodes, forward references, and cyclic graphs while verifying function-local closure and cloning the graph deterministically.
