Owen Anderson 152d063ccb Major think-o. Iterate over all live out-of-loop values, and perform the 
other calculations on each individually, rather than trying to delay it and do
them all at the end.

Reid Spencer 497120ef63 Fix a problem where dejagnu won't accept the value of global tcl variable 
"libdir" for some reason. Changing to llvmlibsdir instead fixes it.

Reid Spencer 633301acea Provide an infrastructure for testing the llvm2cpp program (yet to be 
committed). This infrastructure is only activated when RUNLLVM2CPP=1 is
specified on the make command line. Currently it is only supported in the
Feature test suite.

Owen Anderson 1310e42803 Make LCSSA insert proper Phi nodes throughout the rest of the CFG by computing 
the iterated Dominance Frontier of the loop-closure Phi's.  This is the
second phase of the LCSSA pass.  The third phase (coming soon) will be to
update all uses of loop variables to use the loop-closure Phi's instead.

Chris Lattner be853d77e9 Switch the inliner over to using CloneAndPruneFunctionInto. This effectively 
makes it so that it constant folds instructions on the fly.  This is good
for several reasons:

0. Many instructions are constant foldable after inlining, particularly if
   inlining a call with constant arguments.
1. Without this, the inliner has to allocate memory for all of the instructions
   that can be constant folded, then a subsequent pass has to delete them.  This
   gets the job done without this extra work.
2. This makes the inliner *pass* a bit more aggressive: in particular, it
   partially solves a phase order issue where the inliner would inline lots
   of code that folds away to nothing, but think that the resultant function
   is big because of this code that will be gone.  Now the code never exists.

This is the first part of a 2-step process.  The second part will be smart
enough to see when this implicit constant folding propagates a constant into
a branch or switch instruction, making CFG edges dead.

This implements Transforms/Inline/inline_constprop.ll

Chris Lattner 8f872d2091 Fix a nasty dag combiner bug that caused nondeterminstic crashes (MY FAVORITE!): 
SimplifySelectOps would eliminate a Select, delete it, then return true.

The clients would see that it did something and return null.

The top level would see a null return, and decide that nothing happened,
proceeding to process the node in other ways: boom.

The fix is simple: clients of SimplifySelectOps should return the select
node itself.

In order to catch really obnoxious boogs like this in the future, add an
assert that nodes are not deleted.  We do this by checking for a sentry node
type that the SDNode dtor sets when a node is destroyed.

Chris Lattner 608290c299 Add a new sentry node type, allowing assertions to catch trivial

Evan Cheng 21dee4e0b2 Make CALL node consistent with RET node. Signness of value has type MVT::i32 
instead of MVT::i1. Either is fine except MVT::i32 is probably a legal type
for most (if not all) platforms while MVT::i1 is not.
