provide re-usable forms of the rest of the custom validation done here.
Still no functionality changed here.

With this it should be possible to have an expression-centric code path
and a type-centric code path which don't duplicate logic.

It has little overlap with other traits' requirements, so the resulting
code is actually simpler.

traits which uses the information embedded in the expression. Use this
to simplify several interfaces which repeated information embedded in
the expression through explicit arguments. I added an assertion that the
only extra piece of data to come in from the parser matches what is
stored in the expression. No functionality change intended here.

Also cleaned up the doxygen comments for some of these methods and some
formatting oddities.

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.

makes it into a special member function. This is very bad and can lead
to all sorts of nastiness including implicit member functions violating
the One Definition Rule. This should probably be made ill-formed in a
later version of the standard, but for now we'll just warn.

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.

Skip extra copy from aggregate where it isn't necessary; rdar://problem/8139919 .  This shouldn't make much of a difference at -O3, but should substantially reduce the number of generated memcpy's at -O0.

Originally r130717, but was backed out due to an ObjC regression.

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.

static analyzer: when conservatively evaluating functions, don't invalidate the values of globals when the called function is strlen.

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).

Add a little spice to the script to allow us to specify a function name to break at and to disassemble.

Usage: disasm.py [-n name] executable-image
       By default, it breaks at and disassembles the 'main' function.

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.
