This patch fixes type traversal to avoid compiler crashes for test
cases where a type T includes an expression that refers back to the
type without actually explicitly mentioning T. Examples include
var x [uintptr(unsafe.Sizeof(&x))]byte
var a [len(a)]int
The fix involves expanding the set of types that the traversal code
"remembers" (to avoid cycles) to include array types, and introducing an
additional guard in Builtin_call_expression::do_is_constant to catch
cyclic type constructs.

README
This directory contains the GNU Compiler Collection (GCC). The GNU Compiler Collection is free software. See the files whose names start with COPYING for copying permission. The manuals, and some of the runtime libraries, are under different terms; see the individual source files for details. The directory INSTALL contains copies of the installation information as HTML and plain text. The source of this information is gcc/doc/install.texi. The installation information includes details of what is included in the GCC sources and what files GCC installs. See the file gcc/doc/gcc.texi (together with other files that it includes) for usage and porting information. An online readable version of the manual is in the files gcc/doc/gcc.info*. See http://gcc.gnu.org/bugs/ for how to report bugs usefully. Copyright years on GCC source files may be listed using range notation, e.g., 1987-2012, indicating that every year in the range, inclusive, is a copyrightable year that could otherwise be listed individually.
