Fix the global string bug for printf.
When there are multi printf statements in multi kernel
fucntions within the same translate unit, if they have
the same sting parameter, the Clang will just generate
one global string named .strXXX to represent that string.
So when translating the kernel to gen, we can not unref

We bind each surface to a dedicated bti. HW provides automatic
bounds check. For out-of-bound write, it will be ignored. And for read
out-of-bound, hardware will simply return zero value.
The idea behind the patch is for a load/store instruction, it will search
through the LLVM use-def chain until finding out where the address
comes from. Then the bti is saved in ir::Instruction and used for
the later code generation. And for mixed pointer case, a load/store
will access more than one bti.

'1' is reserved for private address space. Other btis are assigned

runtime: fix some subtle event bugs.
This patch fix the following two bugs in event handling.
1. When it's time to call a event's user call back function, we need to
set the executed to true before the call. As that call back function
may call into clReleaseEvent(), and if we don't set the executed status
to true, it will enter infinite recursive loop.
2. After the user call clEnqueueNDRangeKernel to get a valid event, the
user set a call back function to that event, and in that call back
function, it will release that event. This scenario is totally correct.
But our current event handling doesn't have a deadicated timer thread to
update those on-the-fly events' status. Thus those events will not have
a chance to get updated, and those call back function will not executed
forever. To introduce a complete timer style thread to maintain this type
of events is too heavy for this fix release. This patch choose an easy
way to work around it. It will make sure the last gpgpu event to be finished

runtime: fix potential curbe allocation issue.
According to spec, different platforms have different curbe
allocation restrication. The previous code set the curbe
allocated size to 480 statically which is not correct.
This patch change to always set the curbe entry num to 64
which is the maximum work group size. And set proper curbe
allocation size according to the platform's hard limitation
and a relatively reasonable kernel argument usage limitation.
v3:
when we call load_vte_state, we already know the eaxctly constant urb
size used in the current kernel. We could choose a smallest valid curbe
size for this kernel. And if the size exceed the hardware limitation,
we report it as a warning here.

runtime: fix max group size calculation issue.
If the kernel doesn't use slm/barrier, there is no hard limitation
for the max group size. And if the max work group size is more than
1024, the original 64 urb entry count will not be sufficient to hold
all the curbe payload. Change the entry count to max thread count to
fix this potential issue.
I found this bug when I tried to run phoronix test suite's juliagpu
test case on my MBA.
v2:
refine the max kernel work group size calculation mechanism.
the wg_sz should not be a device's member variable, it should be
a variable derived from kernel and device's attriute at runtime.
also fix wrong configuration for IVB GT1.
v3:
Add an important max thread limitation in the GPGPU_WALKER command.
For non-Baytrail, the max thread depth * max thread height * max thread width
should less than 64 (under either simd16 or simd8), no matter whether
SLM/barrier is used. We oversighted that limitation before, thus for
a simd8 kernel which use work group size 1024 will exceed this limitation
and half of the thread will not be executed at all.
