[svn r360] Another mostly rewrite of DtoArrayInit. Should be much more robust now, and probably faster code generated for the most common cases too! Fixed issues with slice initialization (!!!) of multidimensional static arrays. Attempt to fix issue with referencing nested 'this' pointers introduced in DMD 1.033 merge.

module bug17;

struct Vec
{
    Vec opAdd(ref Vec b) { return Vec(); }
    Vec opMul(double a) { return Vec(); }
}
void main()
{
    Vec foo;
    Vec bar;
    auto whee=foo+bar*1f;
}
