[svn r374] Move label target basic block from AST to IRFunction. This is a first step to allowing labels to be emitted multiple times. (for instance within finally blocks)

module mainargs1;

extern(C) int printf(char*,...);

void main(char[][] args)
{
    foreach(v; args)
    {
        printf("%.*s\n", v.length, v.ptr);
    }
}
