in the 32-bit signed offset field of addresses. Even though this may be intended, some linkers refuse to relocate code where the relocated address computation overflows. Also, fix the sign-extension of constant offsets to use the actual pointer size, rather than the size of the GlobalAddress node, which may be different, for example on x86-64 where MVT::i32 is used when the address is being fit into the 32-bit displacement field. git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@57885 91177308-0d34-0410-b5e6-96231b3b80d8
