1ab79897e2 Avoid storing and reloading zeros and other constants from stack slots 
by flagging the associated instructions as being trivially rematerializable.

588af2fb99 Add support for having different alignment for objects on call frames. 
The x86-64 ABI states that objects passed on the stack have
8 byte alignment. Implement that.

8806c7b1f5 Split eh.select / eh.typeid.for intrinsics into i32/i64 versions. This is needed, because they just "mark" register 
liveins and we let frontend solve type issue, not lowering code :)
