[Bug c++/21454] New: const array doesn't live in the rodata section in C++

["kazu at cs dot umass dot edu" <gcc-bugzilla at gcc dot gnu dot org>]

Consider:

static const int array[] = { 0, 1, 2, 3 };

int
foo (unsigned int i)
{
  return array[i];
}

I get:

	.file	"test.cc"
	.text
	.align 2
	.p2align 2,,3
.globl _Z3fooj
	.type	_Z3fooj, @function
_Z3fooj:
.LFB2:
	movl	4(%esp), %eax
	movl	array(,%eax,4), %eax
	ret
.LFE2:
	.size	_Z3fooj, .-_Z3fooj
	.data
	.align 4
	.type	array, @object
	.size	array, 16
array:
	.long	0
	.long	1
	.long	2
	.long	3
	.ident	"GCC: (GNU) 4.1.0 20050508 (experimental)"
	.section	.note.GNU-stack,"",@progbits

Note ".data".  We could use ".rodata" for this array.
