Turn on -Wunused and -Wno-unused-parameter. Clean up most of the resulting
fall out by removing unused variables. Remaining warnings have to do with
unused functions (I didn't want to delete code without review) and unused
variables in generated code. Maintainers should clean up the remaining
issues when they see them. All changes pass DejaGnu tests and Olden.

Start eliminating temporary vectors used to create DAG nodes. Instead, pass
...
in the start of an array and a count of operands where applicable. In many
cases, the number of operands is known, so this static array can be allocated
on the stack, avoiding the heap. In many other cases, a SmallVector can be
used, which has the same benefit in the common cases.
I updated a lot of code calling getNode that takes a vector, but ran out of
time. The rest of the code should be updated, and these methods should be
removed.
We should also do the same thing to eliminate the methods that take a
vector of MVT::ValueTypes.
It would be extra nice to convert the dagiselemitter to avoid creating vectors
for operands when calling getTargetNode.

When we legalize target nodes, do not use getNode to create a new node,
...
use UpdateNodeOperands to just update the operands! This is important because
getNode will allocate a new node if the node returns a flag and this breaks
assumptions in the legalizer that you can legalize some things multiple times
and get exactly the same results.

gsm/toast.
