commit e839e6ed99c6b25aee589f56bb58de2f8fa00f41

    Add OP_MULTICONCAT op

    Allow multiple OP_CONCAT, OP_CONST ops, plus optionally an OP_SASSIGN
    or OP_STRINGIFY, to be combined into a single OP_MULTICONCAT op, which can
    make things a *lot* faster: 4x or more.

Best regards,
Sergey Aleynikov
