190d6bc636 Fix PR3274: when promoting the condition of a BRCOND node,
promote from i1 all the way up to the canonical SetCC type.
In order to discover an appropriate type to use, pass
MVT::Other to getSetCCResultType.  In order to be able to
do this, change getSetCCResultType to take a type as an
argument, not a value (this is also more logical).

a0f1fc06c4 Clean up the atomic opcodes in SelectionDAG.
This removes all the _8, _16, _32, and _64 opcodes and replaces each
group with an unsuffixed opcode. The MemoryVT field of the AtomicSDNode
is now used to carry the size information. In tablegen, the size-specific
opcodes are replaced by size-independent opcodes that utilize the
ability to compose them with predicates.

This shrinks the per-opcode tables and makes the code that handles
atomics much more concise.

96d87db03b We have decided not to support inline asm where an output operand with a matching input operand with incompatible type (i.e. either one is a floating point and the other is an integer or the sizes of the types differ). SelectionDAGBuild will catch these and exit with an error.

4c8fb3a0cc Add sub/mul overflow intrinsics. This currently doesn't have a
target-independent way of determining overflow on multiplication. It's very

0f9b6c3524 Rename "ADDO" to "SADDO" and "UADDO". The "UADDO" isn't equivalent to "ADDC"
because the boolean it returns to indicate an overflow may not be treated like
as a flag. It could be stored to memory, for instance.

02db3b99bf Implement the sadd_with_overflow intrinsic. This is converted into
"ISD::ADDO". ISD::ADDO is lowered into a target-independent form that does the
addition and then checks if the result is less than one of the operands. (If it
is, then there was an overflow.)

3fe9fef0da - 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.

  one wasn't checking the proper type size.

08905ed703 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.

c369db13cc Reapply r57699 with a fix to not crash on asms with multiple results. Unlike
the previous patch this one actually passes make check.
