error-checking in glsl-compiler

What's going on here, seems to be that we're running out of memory while
linking the shader (during optimizations, but that's probably just dumb luck).
This makes ralloc_size return a NULL-pointer, which gets dereferenced because
the only guards against NULL-pointers in the compiler seems to be asserts.

The attached patch fixes *that* issue for me, but it doesn't make the test
pass, nor fail gracefully either; all that happens is that piglit itself runs
out of memory, triggering an assert.

Besides, it doesn't seem like exceptions is exactly good style in this project.
So I dunno...
