Add the PCH support when building the source.

Because the utest grows bigger, the runtime compiling time seems a big
problem to cause the utest_run very slow.  Most of the time wastes on
re-parsing the big header file such as ocl_stdlib.h.
Using the PCH feature of Clang can shorten the compiling time a lot.
Because we build the pch file at building time, but some source
has runtime building option for LLVM, and these options may cause
the compitable problem between the pch header and the CL source code.
We fallback to build the whole header and source when we find the
options are not compitable.

v2 from Zhigang:
Based on junyan's patch, I made the following changes and fixing:
1. Change the way to find correct pch file, now we just define
two possible locations of the header file at build time. Don't
need to query the linker to get correct pch file directory.

2. Use python to generate a big blob of all ocl standard headers
into one file.

3. Fix those broken dependencies in the CMakeLists.txt, now it
works fine.

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

Refine the get_local_id/... builtins.

As we could prepare correct value on runtime library side and give
a correct value in the payload for dim 0, 1 and 2. So for these 3
dim argument, we don't need to check it whether in the valid range,
we just read the payload's value.

This way, we can avoid any unecessary branching for normal usage of
