dmd 1.058 and 2.043 release

[bearophile]

Thank you for the release and your work, and thank you to Don for all the bug fixes.
I will need some more time to test this release better. In the meantime, is it possible to use BigInts into an AA? This gives a Range violation:

import std.bigint: BigInt;
void main() {
    BigInt[BigInt] aa;
    aa[BigInt(1)]++;
}

Bye,
