GBE: Clear the value map when start a new scalarize pass.

The scalarize pass is a function pass, and the valueMap should
be a per-function data rather than a per-unit data. The reason
we put it in the unit data structure is that the scalarize pass
is before the GenWriter pass thus there is no ir::Function exists.

As there may be multiple kernel functions in one unit, if we don't
clear the valueMap each time running a new scalarize pass, the previous
data may cause some unexpected behaviour. For example, the previous
instructions have been already erased, then latter a new instruction
in this function may be created in the same position of the erased
instruction, then it breaks this valueMap. That's the root cause why
we run the unit test several times and may encounter an assertion
sometime.

This commit also modify the ir::unit layer implementation to remove
the dependency of llvm from that layer. In general, we should not add

GBE: Fixed one bug in scalarize pass

I met segfault at void Scalarize::dce() randomly when I integrate
a openCL kernel to the chromium's GPU process. After discuss with
Yang Rong, I found one bug in this function. As it use two loops
to erase the dead instructions, but it doesn't set the pointer to
NULL at the first loop when it already erased the instruction. Thus
at the second loop, when it call (*i)->getParent, the (*i) may
already be deleted then it may refer a freed region and may cause
segfault.

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.

        //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.
