The following test case results in an unnecessary spew of invalid errors.

---- a.d ----
void main() { x; }

---- b.d ----
import std.stdio;

---- c.d ----
import std.stdio;
immutable ushort p;
void foo() { writefln("%d", p); }

---- Compile with ----
dmd a.d b.d c.d

---- Output ----
a.d(1): Error: undefined identifier x, did you mean module a?
std/format.d(1205): Error: cannot implicitly convert expression (obj) of type
immutable(ushort) to immutable(bool)
std/format.d(2950): Error: template instance
std.format.formatValue!(LockingTextWriter, immutable(ushort), char) error
instantiating
... lots more similar nonsense errors ...


NOTES:
- The file order in the compile is important, compiling c.d before b.d removes
the issue
- Yes, the b.d file is necessary to repro

Expected behaviour: only the first line of the output should be presented
(undefined identifier x)
