GlobalISel: translate GEP instructions. Unlike SDag, we use a separate G_GEP instruction (much simplified, only taking a single byte offset) to preserve the pointer type information through selection. llvm-svn: 281205

GlobalISel: make G_CONSTANT take a ConstantInt rather than int64_t. This makes it more similar to the floating-point constant, and also allows for larger constants to be translated later. There's no real functional change in this patch though, just syntax updates. llvm-svn: 288712
