Of course it's impossible to increment a read-only property. In this 
case a compiler error should occur.

But TControl.Left is defined as
   property Left: Integer read FLeft write SetLeft;
and could be incremented in preceding FPC versions.

Inc() could work when expanded like a macro, and this is how it seems to 
have behaved in the past.
