GlobalISel: place constants correctly in the entry block. When the entry block was empty after arg lowering, we were always placing constants at the end. This is probably hamrless while translating the same block, but horribly wrong once its terminator has been translated. So switch to inserting at the beginning. llvm-svn: 288720

GlobalISel: simplify MachineIRBuilder interface. MachineIRBuilder had weird before/after and beginning/end flags for the insert point. Unfortunately the non-default means that instructions will be inserted in reverse order which is almost never what anyone wants. Really, I think we just want (like IRBuilder has) the ability to insert at any C++ iterator-style point (i.e. before any instruction or before MBB.end()). So this fixes MIRBuilders to behave like IRBuilders in this respect. llvm-svn: 288980

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
