This test case generated wrong code in 2.053 and earlier, but it actually
should have been accepts-invalid.

Since 2.054 it generates

test.d(3): Error: array cast from string to uint[] is not supported at compile
t
ime
test.d(8): Error: cannot evaluate toArray("\xdd\xcc\xbb\xaa") at compile time
test.d(8): Error: static assert  (toArray("\xdd\xcc\xbb\xaa")[0u] ==
-1430532899
u) is not evaluatable at compile time

https://github.com/D-Programming-Language/dmd/commit/5d6df984d50862f25b481790ad4ef86b0afd6c9a

Also the spec now states that such casts are not legal in CTFE.
