Since dmd r629: ICE(expression.c, 816) occurs when null array is used in
static-if or template constraint.

Repro.
-------------------- test.d
static if (string.init.length > 0)  // null array
{
}
--------------------
% dmd -c -o- test
Assertion failed: (precedence[e->op] != PREC_zero), function expToCBuffer, file
expression.c, line 816.
--------------------

It was a rejects-valid bug 1982 before r629.
--------------------
% dmd-r628 -c -o- test
test.d(1): Error: expression (null.length) > 0u is not constant or does not
evaluate to a bool
--------------------

Assertion failed: (precedence[e->op] != PREC_zero), function expToCBuffer, file

Original test case has been fixed so I'll create a new report. Sorry for the
buzz.
