sema: port decl_literal, inline call ret_ty, CG builtin resolution (num_passing=4)
- Extend ret_ty_body pre-resolution from >2 to >1 instructions,
removing the special-case 2-inst handler in analyzeFuncBodyAndRecord.
All multi-instruction return type bodies now use analyzeBodyInner.
- Generalize builtin_value handler with name table for all 12 types.
- Port zirDeclLiteralComptime for resolving decl_literal ZIR.
Namespace/nav resolution for builtin types is UNIMPLEMENTED.
- Remove hardcoded strcmp dispatch in resolveCgBuiltinField — CG
builtin fields are resolved via normal ZIR evaluation path.
- Add param→arg bindings to inst_map BEFORE analyzing ret_ty body
in semaAnalyzeCall, so @TypeOf(a) etc. can resolve param references
(ported from Sema.zig:7393).
- Replace all silent VOID_VALUE returns for compile-error paths
with SEMA_FAIL macro; replace unimplemented paths with UNIMPLEMENTED.
- Add export_fn_bitcast and xor_const sema tests.
