If llvm.dbg.value and the value instruction it refers to are far apart then iSel may not be able to find corresponding Node for llvm.dbg.value during DAG construction. Make iSel's life easier by removing this distance between llvm.dbg.value and its value instruction.

Rework how the MCWin64EHUnwindInfo instances are stored. Fix issues with
chained unwind areas exposed by the test that were related to this.

The ChainedParent field had the wrong address, because when the chained unwind
info was added, the addresses shifted around. Now we store the pointers to the
structures, which are now allocated from the MC heap.

Use a proper worklist for use-def traversal without holding onto an
iterator. Now that we process all IV uses, we need complete logic for
resusing existing derived IV defs. See HoistStep.

This doesn't change functionality (much), but it allows for a more fine-grained
eviction policy. The current policy only compares spill weights, and that is not
always the best thing to do.  Spill weights are designed to serve linear scan,
and they don't consider live range splitting.

Add a mechanism so canEvict() can request that a live range be evicted and
split/spilled. This is to avoid infinite eviction loops.

Rewrite fast-isel integer cast handling to handle more cases, and to be simpler and more consistent.

The practical effects here are that x86-64 fast-isel can now handle trunc from i8 to i1, and ARM fast-isel can handle many more constructs involving integers narrower than 32 bits (including loads, stores, and many integer casts).

I had to add a special SwitchSectionNoChange method to MCStreamer just for
.seh_handlerdata. If this isn't OK, please let me know, and I'll find some
other way to fix .seh_handlerdata streaming.
