Chandler Carruth 7ec5085e01 Revert the series of commits starting with r166578 which introduced the 
getIntPtrType support for multiple address spaces via a pointer type,
and also introduced a crasher bug in the constant folder reported in
PR14233.

These commits also contained several problems that should really be
addressed before they are re-committed. I have avoided reverting various
cleanups to the DataLayout APIs that are reasonable to have moving
forward in order to reduce the amount of churn, and minimize the number
of commits that were reverted. I've also manually updated merge
conflicts and manually arranged for the getIntPtrType function to stay
in DataLayout and to be defined in a plausible way after this revert.

Thanks to Duncan for working through this exact strategy with me, and
Nick Lewycky for tracking down the really annoying crasher this
triggered. (Test case to follow in its own commit.)

After discussing with Duncan extensively, and based on a note from
Micah, I'm going to continue to back out some more of the more
problematic patches in this series in order to ensure we go into the
LLVM 3.2 branch with a reasonable story here. I'll send a note to
llvmdev explaining what's going on and why.

Summary of reverted revisions:

r166634: Fix a compiler warning with an unused variable.
r166607: Add some cleanup to the DataLayout changes requested by
         Chandler.
r166596: Revert "Back out r166591, not sure why this made it through
         since I cancelled the command. Bleh, sorry about this!
r166591: Delete a directory that wasn't supposed to be checked in yet.
r166578: Add in support for getIntPtrType to get the pointer type based
         on the address space.

Micah Villmow 12d9127833 Add in support for getIntPtrType to get the pointer type based on the address space. 
This checkin also adds in some tests that utilize these paths and updates some of the
clients.

Nadav Rotem 5dc203e8f4 Reapply the TargerTransformInfo changes, minus the changes to LSR and Lowerinvoke.

Bob Wilson d6d9ccca38 Temporarily revert the TargetTransform changes. 
The TargetTransform changes are breaking LTO bootstraps of clang.  I am
working with Nadav to figure out the problem, but I am reverting it for now
to get our buildbots working.

This reverts svn commits: 165665 165669 165670 165786 165787 165997
and I have also reverted clang svn 165741

Chris Lattner e983082bdb remove the InvalidateStructLayoutInfo API, which is dead and unnecessary now 
that type refinement is toast.

Chris Lattner 0e125bb4d0 introduce a new TargetLibraryInfo pass, which transformations can use to 
query about available library functions.  For now this just has 
memset_pattern16, which exists on darwin, but it can be extended for a 
bunch of other things in the future.

Chris Lattner 25963c6113 "In order to ease automatic bindings generation, it would be helpful if boolean values were distinguishable from integers. The attached patch introduces "typedef int LLVMBool;", and uses LLVMBool instead of int throughout the C API, wherever a boolean value is called for." 
Patch by James Y Knight!

Duncan Sands af9eaa830a Rename PaddedSize to AllocSize, in the hope that this 
will make it more obvious what it represents, and stop
it being confused with the StoreSize.
