Owen Anderson 333c400965 This started as a small change, I swear. Unfortunately, lots of things call the [I|F]CmpInst constructors. Who knew!?

Duncan Sands 777d2306b3 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.

Bill Wendling 5601699d7c When we split a basic block, there's a default branch to the newly created BB.
Delete this default branch, because we're going to generate our own.

Duncan Sands ceb4d1aecb Rename getABITypeSize to getTypePaddedSize, as
suggested by Chris.

Bill Wendling 733bbc5320 Remove the stackprotector_check intrinsic. Use a volatile load instead.

Bill Wendling c3348a77f7 - Use "moveAfter" instead of "remove/insert" of a basic block.
- Use less indentation in coding.
- Shorten description.
- Update comments.
- Move code around

Bill Wendling e9e6bdf27f Implement stack protectors as function attributes: "ssp" and "sspreq".

Bill Wendling 22511ed2fe Small simplification. Use the iterator already present as the insertion point.

Bill Wendling 7205677a46 - Make sure that we don't over-increment the iterator when going through the
basic blocks.
- Minor code clean-up.

Bill Wendling b7c6ebcb47 - Modify the stack protector algorithm so that the stack slot is allocated in
LLVM IR code and not in the selection DAG ISel. This is a cleaner solution.

- Fix the heuristic for determining if protectors are necessary. The previous
  one wasn't checking the proper type size.

Bill Wendling 1fb615f820 Don't build a vector of returns. Just modify the Function in the loop.

Bill Wendling 703ccfe053 The size limit is for individual arrays. So if any array has more than 8 bytes
in it, then emit stack protectors.

Bill Wendling 4c3a1d8d2b - Rename stackprotector_{prologue,epilogue} to stackprotector_{create,check}.
- Get rid of "HasStackProtector" in MachineFrameInfo.
- Modify intrinsics to tell which are doing what with memory.

Bill Wendling 89c5cc6c79 Adjust the stack protector heuristic to care about only arrays or calls to
"alloca".

Bill Wendling b2a4298ce4 Implement the stack protector stack accesses via intrinsics:
- stackprotector_prologue creates a stack object and stores the guard there.

- stackprotector_epilogue reads the stack guard from the stack position created
  by stackprotector_prologue.

- The PrologEpilogInserter was changed to make sure that the stack guard is
  first on the stack frame.

Bill Wendling 613f77439e Some code simplification. It now doesn't generate a prologue if the epilogue
isn't going to be generated.
