[ILK] GPU hang (and multiple fails) in piglit shader tests if spilling is forced in the vec4 backend

Description
Running piglit's shader tests (~14000 tests) while forcing spilling on the vec4 backend (INTEL_DEBUG=spill_vec4) produces at least one GPU hang (for me this happens consistently around test 10400). Also, I see a lot of tests that stop passing, even before the GPU hang, which points at something seriously broken. The FS backend is not affected, even if INTEL_DEBUG=spill_fs is used to force spilling.
All this is with current master (1614c39a)
To reproduce:
INTEL_DEBUG=spill_vec4 ./piglit-run.py tests/shader results/shader
I'll see if I can add more info, at least the specific test triggering the hang.
