1.the "const" associated functions' modification is to fix "type qualifier on return type is meaningless" for ICC compile warning.
2.the "operator new" shoud have the corresponding "operator delete" function.
3.In C++0x std::auto_ptr will be deprecated in favor of std::unique_ptr.

Fail gracefully on unsupported hardware
If no compatible hardware is present, clGetDeviceIDs is supposed to
report CL_DEVICE_NOT_FOUND to the caller, but in Beignet this currently
ends the whole program with exit(-1) or assert(0). This fixes this.
This is required to have a "just works" OpenCL in Debian/Ubuntu, as
their package manager doesn't know the hardware and hence commonly will
install Beignet on hardware that doesn't support it; returning an error
allows the caller to try other ICDs until it finds the right one, or to
run without using OpenCL. Previous discussion:

GBE: Refine bti usage in backend & runtime.
Previously, we simply map 2G surface for memory access,
which has obvious security issue, user can easily read/write graphics
memory that does not belong to him. To prevent such kind of behaviour,
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.
To simplify some code, '0' is reserved for constant address space,
'1' is reserved for private address space. Other btis are assigned
automatically by backend.
