astgen: add missing emitDbgNode for if condition

Browse Source 
Port the emitDbgNode(parent_gz, cond_expr) call from upstream
AstGen.zig:6335 into ifExpr. This emits a DBG_STMT instruction
before evaluating the if condition, matching the reference output.

Enable astgen_test.zig corpus test (still has extra_len and
string_bytes mismatches to fix).
