e73f31f526 Some code simplification. It now doesn't generate a prologue if the epilogue 
isn't going to be generated.

c162a200ad Add a new pass to simplify specific half_powr function calls. This is 
a specialized pass that it not likely to be generally useful.

a5d766c285 fix memory leak in pass manager when adding an analysis pass that already existed. as pass manager takes ownership of the added passes, it has to delete the pass if it isnt added to the pass list 
tweak the opt tool so that it doesnt access a Pass after the ownership was taken by the pass manager

79a8798e07 - Add a "getOrInsertGlobal" method to the Module class. This acts similarly to 
"getOrInsertFunction" in that it either adds a new declaration of the global
  and returns it, or returns the current one -- optionally casting it to the
  correct type.
- Use the new getOrInsertGlobal in the stack protector code.
- Use "splitBasicBlock" in the stack protector code.

ae168b2c83 Update in response to feedback from Chris: 
- Use enums instead of magic numbers.

- Rework algorithm to use the bytes size from the target to determine when to
  emit stack protectors.

- Get rid of "propolice" in any comments.

- Renamed an option to its expanded form.

- Other miscellanenous changes.

More changes will come after this.

28e234a959 For some targets, it's not possible to place GVs in the same memory buffer as the MachineCodeEmitter allocated memory. Code and data has different read / write / execution privilege requirements. 
This is a short term workaround. The current solution is for the JIT memory manager to manage code and data memory separately.

0f3f36688b Initial checkin for stack protectors. Here's what it does: 
* The prologue is modified to read the __stack_chk_guard global and insert it
  onto the stack.

* The epilogue is modified to read the stored guard from the stack and compare
  it to the original __stack_chk_guard value. If they differ, then the
  __stack_chk_fail() function is called.

* The stack protector needs to be first on the stack (after the parameters) to
  catch any stack-smashing activities.

Front-end support will follow after a round of beta testing.

0ba8aad1af The ANDMask node folds to a constant, and isn't the node that needs to 
have its node id set. The new and and shift nodes are the nodes that need
the IDs. This fixes PR2982.
