0b246f3dbd * converted Boolean8 to an internal type, and mapped Boolean to the 
new internal pasbool1(type) (part of mantis #34411)
   o apply the _Bool x86-64 parameter passing rules only to pasbool1

199b5809a3 * optimize "dynarr := dynarr + [elem]" to "Insert(elem, dynarr, High(SizeInt))" and "dynarr := [elem] + dynarr" to "Insert(elem, dynarr, 0)" (we need to do this in the typecheck of taddnode as otherwise the array constructor is already converted) 
+ added test
