Summary: In RewriteStatepointsForGC pass, we create a gc_relocate intrinsic for each relocated pointer, and the gc_relocate has the same type with the pointer. During the creation of gc_relocate intrinsic, llvm requires to mangle its type. However, llvm does not support mangling of all possible types. RewriteStatepointsForGC will hit an assertion failure when it tries to create a gc_relocate for pointer to vector of pointers because mangling for vector of pointers is not supported. This patch changes the way RewriteStatepointsForGC pass creates gc_relocate. For each relocated pointer, we erase the type of pointers and create an unified gc_relocate of type i8 addrspace(1)*. Then a bitcast is inserted to convert the gc_relocate to the correct type. In this way, gc_relocate does not need to deal with different types of pointers and the unsupported type mangling is no longer a problem. This change would also ease further merge when LLVM erases types of pointers and introduces an unified pointer type. Some minor changes are also introduced to gc_relocate related part in InstCombineCalls, CodeGenPrepare, and Verifier accordingly. Patch by Chen Li!
