Renaming this from
"ICE (Assertion failure: '0' on statement.c:123) with delegate literal and CTFE
mixin."

This has nothing to do with delegate literals. Here's a simpler test case:
----
void main() {
    mixin(null);
}
---
On DMD 1.030, this produces:
bug.d(3): Error: argument to mixin must be a string, not (null)

but on DMD 2, it ICEs with:
bug.d(3): Error: argument to mixin must be a string, not (null)
Statement::blockExit(009988FC)
mixin(null);

Assertion failure: '0' on line 123 in file 'statement.c'

abnormal program termination


Interestingly,
----
mixin(null);
---
produces an error on *both* DMD1 and DMD2:

attribute argument to mixin must be a string, not (null)

which has a missing line number. So there are two different but related bugs,
one on DMD 2 only, one which is common.
