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.

c87bf389dc remove the DisablePatternForFastISel predicate, which is a check 
that predated -fast-isel which attempted to speed up the dag pattern
matchers at -O0.  Since fast-isel is around, this is basically 
obsolete and removing it shrinks the generated dag isels.

ce947366ec 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.
