GBE: fixed a barrier related bug.
Actually, this commit fixed two bugs related to barrier.
1. We should set useSLM to true if we use barrier.
2. We need to set barrier id to the barrierMsg payload according to
r0.2. And we don't need to reprogram the barrierCount.
And after this fix, we don't need the work around for the local
memory barrier, thus we don't need the memory fence for local memory
barrier.

Refine error check in SetKernelArg() and support NULL buffer argument
1. refine error check in clSetKernelArg() to follow spec.
2. add support NULL buffer as argument, so user could write like below:
__kernel void func(__global int * p1, constant int* p2) {
if(p1) {
//do some thing if p1 is not NULL.
} else {
//do other things if p1 is NULL
}
}
Then calling clSetKernelArg(k, 0, sizeof(cl_mem), NULL);
3. as there maybe small possibility that we get a 0 starting address for bo,
we add an assert() to make sure we do not get a 0 addressed bo.

mov (8) r6.0<1>:d acc0:d // Low 32 bits
The mul and mach instructions must have all channels enabled.
The first mov should have channel enable from the destHI of IMUL,
the second mov should have the channel enable from the destLO of IMUL.
We need to disable the predication and the mask rather than only set noMask to 1.
The strange thing here is for the first quarter, it seems we don't need to do so.
As change both quarter to this style will waste some registers which cause some
kernels fail to compile (compiler_box_blur.cl), I just change the second quater
to fully comply with bspec here. And in practice, it works fine with all unit
