feat(joinir): Phase 49-3.2 merge_joinir_mir_blocks full implementation
Implement actual block merging for JoinIR Frontend mainline integration: - Block ID remapping: Allocate new IDs from block_gen for all JoinIR blocks - Value ID remapping: Allocate new IDs from next_value_id() for all values - Instruction cloning: Clone all instructions with remapped IDs - Return→Jump conversion: Convert Return terminators to Jump to exit block - Control flow wiring: Jump from current block to JoinIR entry Helper functions added: - collect_values_in_block(): Collect all ValueIds in a block - collect_values_in_instruction(): Collect all ValueIds in an instruction - remap_instruction(): Remap ValueIds and BlockIds in an instruction A/B tests (3 total): - phase49_joinir_mainline_pipeline_smoke - phase49_joinir_mainline_fallback_without_flag - phase49_joinir_mainline_ab_comparison (Route A vs Route B) 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
