gollvm: sync with LLVM trunks

LLVM trunk D64183 wrapped MachineModuleInfo as MachineModuleInfoWrapperPass.
Trunk D68142 changed the argument type of LoadInst::setAlignment function from
unsigned to llvm::MaybeAlign.
Trunk D68268 changed the argument type of StoreInst::setAlignment function from
unsigned to llvm::MaybeAlign.
Trunk D68297 removed the second argument of function llvm::removeUnreachableBlocks.

This CL syncs gollvm with these four LLVM trunks.
