Because IntToStr(Value: Integer) is faster (and smaller) than
IntToStr(Value: Int64) - Delphi (apart from Delphi.NET) generates code for
32-bit processors, and thus any 64-bit code will require more CPU cycles.
The linker is also able to optimise out the functions that are not
referenced, thus if IntToStr(Value: Int64) is not referenced, there is no
need for the function to live in the EXE.
Furthermore, by declaring two overloaded functions, code completion shows
both implementations - which more clearly identifies the purpose of
IntToStr. Showing IntToStr as taking an Int64 parameter only can
potentially be confusing to someone who is new to Delphi.
