15.3
Item 13 says

The exception being handled shall be rethrown if control reaches the
end of a handler of the function-try-block of a constructor or
destructor. Otherwise, the function shall return when control reaches
the end of a handler for the function-try-block

Does the first part mean that the rethrow point is Location A and code
at and below Location B is never executed.

A::A()
{
 try
 {
  // do something
 }
 catch (someexception)
 {
  // do something
 }  // <-- Is this the RETHROW point?  Location A
 // Any code here not executed ?? Location B
}

Does the second part mean that Location C is the return point and the
code at location D is never executed?!?!?

func1()
{
 try
 {
  // do something
 }
 catch (someexception)
 {
  // do something
 } // <-- Is this the return point?!?! Location C
 // More code. Location D
}

No, because there is no function-try-block in the following code.

A function try block is a new feature introduced by the standards
committee, and in all likelyhood not supported by your compiler.  Since
the handler in a function try block is situated outside of the function
(constructor, destructor), it is good that the standard will say what
happens when you reach the end of it.

I like the idea of function try blocks, which are really needed only
for contructors and destructors. The function try block, allows these
special functions to handle exceptions that arise outside the
function body (i.e. in the contructor/destructor of a member or a
base class). Previously this was impossible.
