[Beignet] [PATCH 10/57] Add compiler API to runtime.

[junyan.he at inbox.com]

From: Junyan He <junyan.he at intel.com>

The cl_compiler define common APIs for backend compiler.
The OpencL build, compile and link API will call these
APIs to generate the binary.
This is also useful when wen need to unload the compiler.
