simple_overflow example had a dynamic array in it for temporary purposes, but was in the repo. Reverted this in the source and recompiled the binary.

PrecedenceBoundaryInference.cpp, no canaries for these inferences, reveted to no validation for precedence inference.

Assert false if the info annot file cannot be opened (likely will have to change this in a subsequent commit).

Memset inferences have been shown to be unsafe, they are no longer attempted without validation.

In pntransformdriver, if the current inference is at the lowest level in the hierarchy, then do not perform validation.

PrecedenceBoundaryInference based on p1 did not add an out args region as necessary. Now if precedence bounds sees the supplied inference out args is 0, it assumes the first object is an out args region to be conservative.

PrecedenceBoundaryInference now takes boundaries from a boundary generator, converts them to esp bounds, then produces a "transitive closure" on these ranges. That is, if any ranges intersect, containing all intersections is what is used for the boundary inference.

Changed padding to be a random amount of padding plus size equal to the aligned size of the allocated stack.

Added changes to allow padding between dynamic sized arrays, not between the rest of the variables though (i.e., the transform is essentilaly part PN and part P1).

OffsetInference.cpp, the dynamic stack output log code now checks to see if the file is opened before writing.

OffsetInference.cpp, keeping with the last change to output a dynamic_stack.log, I do a check for null pointers before attempting to print the address of the isntruction. I don't think this can happen, but I don't want to break TNE. 



Former-commit-id: 9a9c34bbdbb9ad5032c5354257fed5be1a6d0122

in OffsetInference.cpp if a dynamic stack frame is detected, a log file, dynamic_stack.log, is created, which lists the functions, addresses, and instructions indicating a dynamic stack frame.

Due to some stupidity, OffsetInference.cpp had lost a previously made change to avoid adding too much padding to recursive functions. This functionality has been restored.

OffsetInference bug fix, do not transform functions that deallocate the stack by a different ammount used for allocation.

OffsetInference looks for recursive functions, if found a flag is set, and when padding is added to that function, the padding is significantly reduced.

If a function is not believed to have a dynamic stack frame, canary checks are performed prior to any function call.
