500425ac7b bug300: literal types must not be parenthesized

07cc6440dc go_spec: don't allow parens around the literal type of composite literals 
Background: The current spec is imprecise with respect to the parsing ambiguity
for composite literals: It says that the ambiguity arises when the TypeName form
of the LiteralType is used. The following code:

    if (B) {} ...

is not using the TypeName form (but the parenthesized TypeName form) and thus
could be interpreted as:

    if ((B){}) ...

instead of

    if B {} ...

Both compilers and gofmt choose the latter interpretation. One could fix the
spec by making the clause regarding the parsing ambiguity more precise ("...using
the _possibly parenthesized_ TypeName form of the LiteralType..."). The alternative
(chosen here) is to simply disallow parenthesized literal types. Except for a single
test case (test/parentype.go) there appears to be no Go code under $GOROOT containing
parenthesized literal types. Furthermore, parentheses are never needed around a
literal type for correct parsing.

1ea5d15407 test/sigchld.go: use syscall.Kill instead of a combination 
of syscall.Syscall and syscall.SYS_KILL.

In RTEMS, there is no syscall.Syscall support, but it does
support POSIX signals. So, if this testcase is changed to use
syscall.Kill, then it would run fine on RTEMS, when using gccgo.

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.

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)) }

b9caa4ac56 big: completed set of Int division routines & cleanups 
- renamed Len -> BitLen, simplified implementation
- renamed old Div, Mod, DivMod -> Que, Rem, QuoRem
- implemented Div, Mod, DivMod (Euclidian definition, more
  useful in a mathematical context)
- fixed a bug in Exp (-0 was possible)
- added extra tests to check normalized results everywhere
- uniformly set Int.neg flag at the end of computations
- minor cosmetic cleanups
- ran all tests

58e77990ba big: use fast shift routines 
- fixed a couple of bugs in the process
  (shift right was incorrect for negative numbers)
- added more tests and made some tests more robust
- changed pidigits back to using shifts to multiply
  by 2 instead of add

  This improves pidigit -s -n 10000 by approx. 5%:
