instantiation history in an effort to speed up c99-intconst-1.c.
Now that multiple nested instantiations are allowed, we just
make them and don't pay the cost of lookups.  With the other
changes that went in before this, reverting this is actually
a speedup for c99-intconst-1.c, speeding it up from 1.96s to 1.80s,
and preserves much better loc info.

Token now has a class of kinds for "literals", which include 
numeric constants, strings, etc.  These tokens can optionally have
a pointer to the start of the token in the lexer buffer.  This 
makes it faster to get spelling and do other gymnastics, because we
don't have to go through source locations.

This change is performance neutral, but will make other changes
more feasible down the road.

This allows us to turn on reconstruction in the pre alloc splitter, which
fixes a number of miscompilations.

Enhance logic in X86DAGToDAGISel::PreprocessForRMW which move load inside callseq_start to allow it to be folded into a call. It was not considering the cases where a token factor is between the load and the callseq_start.

With this patch, chained assignments happen to the right object.

cocoa.h because it shrinks the SLocEntry union, which
we have a big array of.  It would be nice to use 
PointerIntPair here, but we can't because it is in a
