The sign information was not propagating into the rename map so only the
...
last entry stored in the map could be retrieved for a given integer type.
Propagating the sign information required an invasive change to ensure that
all ValueRef (ValID) instances get the right sign information as well. Also,
put in some assertions to ensure the RenameMap always gives us out the type
that is expected.
This fixes PR1256 and

Estimate a cost using the possible number of scratch registers required and use
...
it as a late BURR scheduling tie-breaker.
Intuitively, it's good to push down instructions whose results are liveout so
their long live ranges won't conflict with other values which are needed inside
the BB. Further prioritize liveout instructions by the number of operands which
are calculated within the BB.

Try schedule def + use closer whne Sethi-Ullman numbers are the same.
...
e.g.
t1 = op t2, c1
t3 = op t4, c2
and the following instructions are both ready.
t2 = op c3
t4 = op c4
Then schedule t2 = op first.
i.e.
t4 = op c4
t2 = op c3
t1 = op t2, c1
t3 = op t4, c2
This creates more short live intervals which work better with the register
allocator.
