Explicit cast of a void pointer to a pointer type in different address space is incorrectly classified as bitcast, which causes invalid bitcast in codegen. The patch fixes that by checking the address space of the source and destination type and set the correct cast kind. Differential Revision: https://reviews.llvm.org/D50003 llvm-svn: 338805
