More ^^ related improvements.

Added constant folding on raised powers of integers in frontend (so don't need to rely on importing std.math).
Handle ^^ array operations in backend (bugzilla6548).

Nice. We will need to add some tests (ctorpowtests.d has the existing ones). Should be enough to have most of them of the form
static assert(2^^8 == 256);

[ibuclaw]

Should I bundle them up into ctorpowtests, or create a new test that doesn't import std.math?

Also, given that (x ^^ 0.5) and x is known at compile time, would it be ok to call eval_builtin(sqrt) directly knowing that it is a compiler builtin and not require to setup a call to .std.math.sqrt?

Was thinking of putting it below here: ibuclaw@411010b#L0R558

I'll put them into constfold - and ensure that the std.math import only pulls in what it needs.

Will finish this over the weekend.

On passing, had noticed a typo in checking which value is negative (whoops). Fixed that.
