c2385a0741 Split the main for-each-use loop again, this time for GenerateTruncates,
as it also peeks at which registers are being used by other uses. This
makes LSR less sensitive to use-list order.

f463d9554b Reapply 96294; now that I've gotten around to looking
at older buildbot messages, I see the failure predates
this patch.

2e2b438242 Something broke. Hard to believe it was this patch
but it's harder to believe it's the other candidate,
so reverting.  Temporarily I hope.

7dc9747e89 Put repeated empty pattern into the AQI instruction class.
We could almost use a multiclass for the signed/unsigned instructions, but
there are only 6 of them so I guess it's not worth it.

ac8a3d0b5b It turns out that we emitted completely wrong common EH frame since the early beginning! The "z" CIE augmentation mark indicates that there is an extra word containing the size of augmentation section. However, even for frames w/o any augmentation data we emitted size uleb! (this is the case of "unwinding through C code"). Thus frame moves information was emitterd completely wrong.

014bf215c3 Split SelectionDAGISel::IsLegalAndProfitableToFold to
IsLegalToFold and IsProfitableToFold. The generic version of the later simply checks whether the folding candidate has a single use.

This allows the target isel routines more flexibility in deciding whether folding makes sense. The specific case we are interested in is folding constant pool loads with multiple uses.

da272d1a70 Check in the first big step of rewriting DAGISelEmitter to
produce a table based matcher instead of gobs of C++ Code.

Though it's not done yet, the shrinkage seems promising,
the table for the X86 ISel is 75K and still has a lot of 
optimization to come (compare to the ~1.5M of .o generated
the old way, much of which will go away).

The code is currently disabled by default (the #if 0 in
DAGISelEmitter.cpp).  When enabled it generates a dead
SelectCode2 function in the DAGISel Header which will
eventually replace SelectCode.

There is still a lot of stuff left to do, which are
documented with a trail of FIXMEs.
