GBE: work around error reporting for unresolved symbols

Beignet currently doesn't have a good error reporting mechanism
for internal passes. Currently, almost all error will cause an
user unfriendly assert. This is ok for most of the cases, but
it is really not good for unresolve symbols error, as it is not
a real compiler internal bug and we should not assert. We should
report it to help user to identify the error and fix that in the
cl kernel.

This patch is just a work around. We will implement a better
error handling in the future to consolidate all this type of
error into the normal error log buffer.

Fix the bug of multi-thread crash

GBE: Add a customized loop unrolling handling mechanism.

By default, the unrolling threshold is relatively small.
Thus some relative large loops which access private array
will not be unrolled, thus those private array can't
be scalarized latter. And the private array is allocated
in stack which is extreme slow for Gen backend currently.

To increase the unrolling threshold for all loops is not
a good idea, as most of the loops don't need to do unrolling
for this purpose and a large unrolling threshold will cause
a big code size and unecessary big register pressure which
may lead to register spilling.

So this patch introduce a trade-off pass to identify those
loops which still have private load/store in the outer most
of the loop. Then add a metadata to it to indicate aggresive
unrolling on those loops. Then do another round loop unrolling.

performance improvement for some cases. I just tested with some
opencv test cases, and observed it can bring 2x to 10x improvement.

GBE: fix a legalize pass bug when bitcast wide integer to incompaitble vector.

Our wide integer legalize pass will assume the source type of a wide
integer must be the same as the final use type. But this is not always
true. The following case is a real example:

      %conv.i.i.14 = sext i8 %usrc0.i.sroa.0.14.extract.trunc to i32
      %call.i.i2.14 = tail call i32 @__gen_ocl_abs(i32 %conv.i.i.14) #5
      %conv1.i.i.14.mask = and i32 %call.i.i2.14, 255

      %2 = bitcast i128 %uret.i.sroa.0.15.insert.insert to <16 x i8>

The wide integer i128 %uret.i.sroa.0.16.insert.insert is from an
i32 integer %conv1.i.i.14.mask. But the use of it is i8 vector
which breaks our assumption.

According to ruiling's good suggestion, we always bitcast the wide integer to
a compatible vector, take the above example:
  %3 = bitcast i128 %uret.i.sroa.0.15.insert.insert to <4 x i32>
Then insert a bit cast instruction to convert it to the original destination

Fit the printf bug in loop

The static analyse for printf can not totally work
when the printf inst is within the loop and the loop
can not be unrolled. This causes the printf just to
print one info for a loop and to lose all the others.
We now increment the exec number every time the printf
inst is triggered. The number is stored for output all
the message later.
The problem is that we can not caculate the exact loops
number for each printf inst. The wrong loop number will
cause the data overwritten. We now assume all the printf
inst are in loop and store the data like this:
| PRINTF1_DATA  PRINTF2_DATA ... | PRINTF1_DATA  PRINTF2_DATA ... | ...
|       DATA_LOOP_ONE            |          DATA_LOOP_TWO         | ...
Although this may cause some space wasted.

Another problem is that we need to decide the size of printf buffer
because the loop upbound can not be caculated. We just set
it yo 1M for small info slot request and 4M for big one.
