Reimplement invocation of offline compilation program

Browse Source 
This change reimplements offline compiler invocation, using a new command
line interface that allows the passing of relevant CL device information
to the offline compiler.  The information that is passed is as follows:

 * CL_DEVICE_ADDRESS_BITS
 * CL_DEVICE_EXTENSIONS
 * CL_DEVICE_IL_VERSION (with --compilation-mode=spir-v only)
 * CL_DEVICE_VERSION

The interface for the offline compiler script is as follows:

   usage: cl_offline_compiler --source FILE --output FILE
                              --cl-device-info FILE --mode MODE
                              -- [BUILD_OPTIONS [BUILD_OPTIONS ...]]

   positional arguments:
     BUILD_OPTIONS          additional options to pass to the compiler

   optional arguments:
     --source FILE          OpenCL C source file to compile
     --output FILE          SPIR-V or binary file to create
     --cl-device-info FILE  OpenCL device info file
     --mode                 compilation mode (spir-v or binary)

The OpenCL C version for compilation is now specified in BUILD_OPTIONS,
as normal for online compilation, i.e. with -cl-std=VERSION.

The cl_offline_compiler program used for offline compilation must
implement the following interface.
usage: cl_offline_compiler --source FILE --output FILE
--cl-device-info FILE --mode MODE
-- [BUILD_OPTIONS [BUILD_OPTIONS ...]]
positional arguments:
BUILD_OPTIONS additional options to pass to the compiler
optional arguments:
--source FILE OpenCL C source file to compile
--output FILE SPIR-V or binary file to create
--cl-device-info FILE OpenCL device info file
--mode compilation mode (spir-v or binary)
The --cl-device-info file is a list of KEY=VALUE pairs containing device
information relevant to the mode of offline compilation in question.
It is of the following form:
# OpenCL device info affecting <SPIR-V|binary> offline compilation:
CL_DEVICE_ADDRESS_BITS=<32|64>
CL_DEVICE_EXTENSIONS="<space separated list of CL extensions>"
CL_DEVICE_IL_VERSION="<space separated list of IL versions>"
CL_DEVICE_VERSION="OpenCL <version> <vendor info>"
