Add ocl-icd - OpenCL Installable Client Driver.

This library provides a way that OpenCL programs can open several
ICD's. The Intel (beignet) and AMD/ATI (Clover for Mesa) OpenCL
implimentations will be build as ICD's. This has as benefit
that programs will not link directly against the OpenCL
implimentation but against ocl-icd. The user needs to manualy
install the OpenCL implimentation they want to use.

devel/ocl-icd/pkg-descr

+OpenCL implementations are provided as ICD (Installable Client Driver). An
+OpenCL program can use several ICD thanks to the use of an ICD Loader as
+provided by this project. This free ICD Loader can load any (free or non
+free) ICD.
