7b1362fa52 Start eliminating temporary vectors used to create DAG nodes. Instead, pass 
in the start of an array and a count of operands where applicable.  In many
cases, the number of operands is known, so this static array can be allocated
on the stack, avoiding the heap.  In many other cases, a SmallVector can be
used, which has the same benefit in the common cases.

I updated a lot of code calling getNode that takes a vector, but ran out of
time.  The rest of the code should be updated, and these methods should be
removed.

We should also do the same thing to eliminate the methods that take a
vector of MVT::ValueTypes.

It would be extra nice to convert the dagiselemitter to avoid creating vectors
for operands when calling getTargetNode.

be2fc7b875 Eliminate some malloc traffic by allocating vectors on the stack. Change some 
method that took std::vector<SDOperand> to take a pointer to a first operand
and #operands.

This speeds up isel on kc++ by about 3%.

1661ffa2eb Revamp the "CSEMap" datastructure used in the SelectionDAG class. This 
eliminates a bunch of std::map's in the SelectionDAG, replacing them with a
home-grown hashtable.

This is still a work in progress: not all the maps have been moved over and the
hashtable never resizes.  That said, this still speeds up llc 20% on kimwitu++
with -fast -regalloc=local using a release build.

f5e160063e 1. Change use of "Cache" to "Default". 
2. Added argument to instruction scheduler creators so the creators can do
special things.
3. Repaired target hazard code.

557d3cacbe Instead of blindly looking past constantexpr casts, actually constant 
fold them.  This correctly truncates constants that are too large for the
destination slot and makes the code easier to understand.  This fixes PR853

10b9edbb69 For PR780: 
1. Move IncludeFile.h to System library
2. Move IncludeFile.cpp to System library
3. #1 and #2 required to prevent cyclic library dependencies for libSystem
4. Convert all existing uses of Support/IncludeFile.h to System/IncludeFile.h
5. Add IncludeFile support to various lib/System classes.
6. Add new lib/System classes to LinkAllVMCore.h
All this in an attempt to pull in lib/System to what's required for VMCore
