[PATCH v2 0/4] MR10775: vbscript: Fix and expand test coverage for BSTR comparison. (alternate)

[Francis De Brabandere (＠francisdb)]

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.
