Issue 4031 - Should be able to access const value-type globals from pure functions

Const value-type globals function the same as immutables, so allow them to be accessed from inside pure functions.

Does this also fix bug 6169? "[CTFE] pure functions cannot compute constants using functions not marked as pure"
http://d.puremagic.com/issues/show_bug.cgi?id=6169
Looks as though it might.

Close, but I had to fix. b135734

No, it doesn't fix 6169.

Walter, your version of this fix allows the following to compile:
int z;
const static int* x;

static this()
{
x = &z;
}

void main() pure
{
auto g = *x;
}
The correct fix is probably to include both the hasPointers and the isDataSeg check.

And again, is there something weird going on that prevents you from doing a normal merge and resolving the conflicts, rather than creating a whole new commit?
Something like the following should work:

git pull git://github.com/yebblies/dmd.git branchname

then you edit to resolve the conflicts
git commit
git push origin
