[Verifier] Assert gc_relocate always return a pointer type Summary: Add an assertion in verifier.cpp to make sure gc_relocate relocate a gc pointer, and its return type has the same address space with the relocated pointer.

; This is to verify that gc_relocate must return a pointer with the same
; address space with the relocated value.
; CHECK: gc.relocate: relocating a pointer shouldn't change its address space
[gc.statepoint] Change gc.statepoint intrinsic's return type to token type instead of i32 type Summary: This patch changes gc.statepoint intrinsic's return type to token type instead of i32 type. Using token types could prevent LLVM to merge different gc.statepoint nodes into PHI nodes and cause further problems with gc relocations. The patch also changes the way on how gc.relocate and gc.result look for their corresponding gc.statepoint on unwind path. The current implementation uses the selector value extracted from a { i8*, i32 } landingpad as a hook to find the gc.statepoint, while the patch directly uses a token type landingpad (http://reviews.llvm.org/D15405) to find the gc.statepoint.
