[svn r229] Updated the object.d implementation to the latest Tango. Fixed a bunch of the built-in typeinfos for arrays, they did not inherit TypeInfo_Array. Applied patch to tango/text/convert/Layout.d by fvbommel, closes #47 . Cleaned up some type code. Replaced uses of llvm::Type with LLType (a typedef), same for Value and Constant. Fixed a few cases where typeinfo for user structs could be emitted multiple times, seems to still be some cases of this :/

module foreach3;

void main()
{
    static str = ['h','e','l','l','o'];
    foreach(i,v; str) {
        printf("%c",v);
    }
    printf("\n");

    foreach(i,v; str) {
        v++;
    }

    foreach(i,v; str) {
        printf("%c",v);
    }
    printf("\n");
}
