a6c7ed5e61 vector support: use vector result types 
Set the result of a vector add node to a vector type.

Ensure that that these vector types are still asignment-compatible with
regular array types (may want to change this when we expose vector types),
and don't remove type conversions from vector types to array types (so the
code generator pass can still rely on the resultdef being a vector type)

33ad038bbb * Avoid some wrong error messages after initial error 
On x86_64-openbsd, cycling with -O3 option fails due to
a wrong warning about uninitialized zeros variable in
compilation of ogbase unit
ogbase.pas(2310,41) Warning: Local variable "zeros" does not seem to be initialized
ogbase.pas(2318,39) Error: Can't evaluate constant expression

The second message is due to the fact that simplify is not
called inside nadd unit if errorcount is non-zero.
  By replacing errorcount<>0 by not codegenerror,
this message disappears.
