Alternate version of !10766 This replaces runtime VT_RESERVED tracking with compile-time is_literal_expr at the AST level: comparison opcodes (equal/nequal/gt/gteq/lt/lteq/case) carry a flag arg with bit 0 = left-literal, bit 1 = right-literal, and var_cmp dispatches on those flags. No runtime stripping, no OP_strip_reserved, and Const references stay non-literal because they're EXPR_MEMBER nodes even though the value is inlined. -- v8: vbscript/tests: Cover BSTR comparison with dispatch-only numeric VTs. vbscript: Match native BSTR-vs-numeric and BSTR-vs-Boolean comparison. vbscript/tests: Cover BSTR comparison literal vs non-literal dispatch. vbscript/tests: Cover BSTR comparison with VT_BYREF and additional numeric VTs. vbscript/tests: Add coverage for BSTR vs numeric comparison. https://gitlab.winehq.org/wine/wine/-/merge_requests/10775
