89192ce4fe test/fixedbugs/bug243.go: instead of closing stdout, 
remove the print statements.

This change is because of the port of gccgo to RTEMS.
These tests use the GCC DejaGNU framework. In some cases,
the tests need to be run on qemu where the status code
cannot be sent back to DejaGNU, so it prints the exit status
by putting a wrapper around the exit and abort calls.

This testcase closes the stdout, and hence prohibits DejaGNU
from knowing the status in such cases, and causes this test
to be wrongly declared as a failure.

x.go:13: cannot use t (type T) as type Reader in assignment:
	T does not implement Reader (Read method requires pointer receiver)
x.go:19: cannot use q (type Q) as type Reader in assignment:
	Q does not implement Reader (missing Read method)

		want Read()
x.go:22: cannot use z (type int) as type Reader in assignment:

d482c163be fmt.Print*: reimplement to switch on type first. 
This shortens, simplifies and regularizes the code significantly.
(Improvements to reflect could make another step.)
Passes all.bash.

One semantic change occurs: The String() method changes
behavior. It used to run only for string formats such as %s and %q.
Instead, it now runs whenever the item has the method and the
result is then processed by the format as a string. Besides the
regularization, this has three effects:

	1) width is honored for String() items
	2) %x works for String() items
	3) implementations of String that merely recur will recur forever

Regarding point 3, example from the updated documentation:
	type X int
	func (x X) String() string { return Sprintf("%d", x) }
should cast the value before recurring:
	func (x X) String() string { return Sprintf("%d", int(x)) }
