backports of reequ & redefine to fasm1

Code:

struc reequ value { local tmp
        tmp equ value ; preserve value for case where "restore ." will trash parts of value
        restore .
        . equ tmp }

Code:

macro redefine statement { local tmp,tmp2
        tmp equ
        tmp2 equ
        irps n,statement \{
                match any,tmp \\{ tmp2 equ tmp2 \n \\}
                match ,tmp \\{ define tmp n\\} \}
        match tmp3,tmp \{
                match tmp4,tmp2 \\{
                        restore tmp3
                        define tmp3 tmp4 \\} \} }

test both of them - works(tested on macroset "struct" where previous value used as part of reequalition/redefinition - in "endp" macro when "match any, sub@struct" tested - content of match block replaced with "redefine field@struct field@struct>" & "field@struct reequ field@struct>").
but maybe second one could be simplified?
