Bug 1914 Array initialisation from const array yields memory trample

was fixed, in D2 only. Can we get this into D1 as well?

To show what a huge difference this bug makes, try this test case for 
large values of N:

Executable size in bytes

N       D2.040   D2.041
---    -------   ------
10      266 Kb   241 Kb
100     306 Kb   241 Kb
2000  16151 Kb   257 Kb
10K  <locks up>  321 Kb
---------
enum : int { N = 1000 }

struct S {
     const float[N] BIGINIT = [7];
     float a[N] = BIGINIT;
}

void main() {}
