10de3bb4fd Do not directly use function names to construct new name for named metadata. 
"llvm.dbg.lv.~A" is not a valid name.

faeb0e7448 More changes for non-top-down fast-isel. 
Split the code for materializing a value out of
SelectionDAGBuilder::getValue into a helper function, so that it can
be used in other ways. Add a new getNonRegisterValue function which
uses it, for use in code which doesn't want a CopyFromReg even
when FuncMap.ValueMap already has an entry for it.

the LocalValueMap, to make it more flexible when fast-isel isn't
proceding straight top-down.

1e3121c80a Include the use kind along with the expression in the key of the 
use sharing map. The reconcileNewOffset logic already forces a
separate use if the kinds differ, so incorporating the kind in the
key means we can track more sharing opportunities.

More sharing means fewer total uses to track, which means smaller
problem sizes, which means the conservative throttles don't kick
in as often.
