Implement FloorDivInt
Create a Bitmap class to encapsulate that functionality

In preparation for using bitmaps for other purposes in the heap.
Merge pull request #224 from undingen/floorDivInt

Implement FloorDivInt
Update to llvm trunk
Right multiplication for list and integer.
Add tuple repeat.
Merge pull request #227 from jvkersch/fix-int-times-list

List right multiplication, tuple multiplication
Fix the behavior of the default print destination

Ie if you override sys.stdout, prints without an explicit destination
will go to the new location.

Also sneak in a couple other bugfixes.
More makefile magic

This time for the llvm configuration.

Sometimes when updating the LLVM directory, we need to reconfigure things.
We don't know that until after we update it, though, but Make will decide
at the beginning whether it needs to be updated or not.  We could always
reconfigure every time we update LLVM (might be ok), or add a helper
target that recursively calls Make after the updating is done (what this
patch does).

This should fix those "C compiler can't generate executables" errors that
come from running two copies of the configure script in parallel.
Hmm that solution ended up rebuilding LLVM every time, try this instead
WIP: AST Interpreter
Bash the existing OSR code into submission for the new AST interpreter

Once we get the AST interpreter in, we can add resume-from-any-point
functionality, which means that we can get rid of the current OSR system.
Maybe we should have done that first, but I thought it would be easy
to get the OSR stuff working.
allow pyston to run from a directory other than pyston

-the Makefile has been moved up from src/Makefile to the top level
-all pyston binaries and unittests (gc, analysis) are also placed in the
top directory
add cmake as an alternate build system
cmake disable debug info for llvm unless ENABLE_LLVM_DEBUG is ON
libpypa git submodule use https instead of ssh
cmake add astprint
add libpypa as cmake subproject
cmake rename check_format, check_pyston to check-format and check-pyston
for consistency
update libpypa submodule to latest
