Régis Crelier a62107cfaf Check for a passed-in type argument vector in the prolog of generic functions.
Do this in unoptimized code only, when --reify-generic-functions is specified.
This is still work in progress, and support in optimizer, in inliner, in DBC,
in kernel to ir, and other areas, will follow.
Many small fixes and added todos.
