This function is used to
- find a database entry
- fill our etna_device_info struct
If no database entry is found we just return false.

We want to fully initialise etna_device_info. We only query the kernel
for these values if the drm driver is recent enough.

Nothing uses it. I *looks* like _mesa_copy_linked_program_data()
copies it somewhere useful however that function is called before

Use the same code as the pointer type. It works with all types and works
with any vector, but we need to handle i1 and v3i16 as special cases,
otherwise LLVM fails when it sees them. The previous code only extracted
the first component, which is not what we want.
