- Changes diagnostics for Blocks to be implicitly const qualified OpenCL v2.0 s6.12.5. - Added and unified diagnostics of some OpenCL special types: blocks, images, samplers, pipes. These types are intended for use with the OpenCL builtin functions only and, therefore, most regular uses are not allowed including assignments, arithmetic operations, pointer dereferencing, etc. Review: http://reviews.llvm.org/D21989 llvm-svn: 275061
