gallivm: Use alloca_undef with array type instead of alloca_array
Use a single allocation of array type instead of the old-style array
allocation for the temp and immediate arrays.
Probably only makes a difference if they aren't used indirectly (so,
if we used them solely because there's too many temps or immediates).
In this case the sroa and early-cse passes can sometimes do some
optimizations which they otherwise cannot.
(As a side note, for the temp reg array, we actually really should
use one allocation per array id, not just one for everything.)
Note that the instcombine pass would actually promote such
allocations to single alloc of array type as well, but it's too late
for some artificial shaders we've seen to help (we don't want to run
instcombine at the beginning due to its cost, hence would need
another sroa/cse pass after instcombine). sroa/early-cse help there
because they can actually eliminate all of the huge shader, reducing
it to a single const output (don't ask...).
(Interestingly, instcombine also removes all the bitcasts we do on that
allocation for single-value gathering, and in the end directly indexes
into the single vector elements, which according to spec is only
semi-valid, but this happens regardless. Another thing instcombine also
does is use inbound GEPs, which is probably something we should do
manually as well - for indirectly indexed reg files llvm may not be
able to figure it out on its own, but we should be able to guarantee
all pointers are always inbound. In any case, by the looks of it
using single allocation with array type seems to be the right thing
to do even for ordinary shaders.)

llvmpipe: Fix random number generation for unit tests
We were never producing negative numbers for signed types.
Also fix only producing half the valid range for uint32, and
properly clamp signed values.
Because this now also properly tests snorm with actually negative
values, need to increase eps for such conversions. I believe these
cannot actually be hit in ordinary operation (e.g. if a snorm texture
is sampled and output to snorm RT, it will still go through snorm->float
and float->snorm conversion), so don't bother to do anything to fix
the bad accuracy (might be quite complex).
Basically, the issue is for something like snorm16->snorm8 that in the
end this will just use a 8 bit arithmetic right shift.
But the math behind it says we should actually do a division by 32767 / 127, which
is ~258, not 256. So the result can be one bit off (values have too large
magnitude), and furthermore, the shift has incorrect rounding (always rounds
down). For positive numbers, these errors have different direction, but
for negative ones they have the same, hence for some values the error will
be 2 bit in the end.
