This is strictly a quality-of-implementation bug, but it does slow down the
C/C++ compiler needlessly.

In particular, the C front-end emits a .ll file containing an explicit list of
all of the zeros in cases like this:

---
int test[10000];
---

Instead, it would make the C front-end more efficient and the gccas tool parse
the result faster if it just emitted the zeroinitializer token.

Fixed.  Testcase here:

Here's another patch that helps:

It is worth noting that fixing this bug allows us to reduce the size of
129.compress/harness.ll from 391M to 137K.  This puts a LOT less pressure on the
.ll file parser. :)
