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!

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.

When complicated expressions are broken down into subexpressions
with multiplication by constants distributed through, occasionally
those subexpressions can include both x and -x. For now, if this
condition is discovered within LSR, just prune such cases away,
as they won't be profitable. This fixes a "zero allocated in a
base register" assertion failure.
