Jim Grosbach b352d76480 To get more thorough testing from llc-beta nightly runs, do dynamic stack
realignment regardless of whether it's strictly necessary.

Jim Grosbach cad78a7634 When the function is doing dynamic stack realignment, the spill slot will be
indexed via the stack pointer, even if a frame pointer is present. Update the
heuristic to place it nearest the stack pointer in that case, rather than
nearest the frame pointer.

Johnny Chen 8107289624 Sorry to break the build.
I was trying to check the WIP file to some local repository, but ended up
checking in the llvm repository.  Oops!

Dale Johannesen 8829fc3a18 When there is a 2-instruction spill sequence, record
the second (store) instruction in SpillSlotToUsesMap
consistently.  I don't think this matters functionally,
but it's cleaner and Evan wants it this way.

Dale Johannesen 14f162d9dc When we generate spill code, then decide we don't need
to spill after all, we weren't handling 2-instruction
spill sequences correctly (PPC Altivec).  We need to
remove the store in this case.  Removing the other
instruction(s) would be goodness but is not needed for
correctness, and isn't done here.  7331562.

Victor Hernandez 0d025421cd Extend getMallocArraySize() to determine the array size if the malloc argument is:
ArraySize * ElementSize
ElementSize * ArraySize
ArraySize << log2(ElementSize)
ElementSize << log2(ArraySize)

Refactor isArrayMallocHelper and delete isSafeToGetMallocArraySize, so that there is only 1 copy of the malloc array determining logic.
Update users of getMallocArraySize() to not bother calling isArrayMalloc() as well.

Chris Lattner fbaac77c70 add a new 'SetCurrentDebugType' API (requested by Andrew Haley for JIT

Chris Lattner 5956dc87d3 add bitcode reader support for blockaddress. We can now fully
round trip blockaddress through .ll and .bc files, so add a testcase.

There are still a bunch of places in the optimizer and other places
that need to be updated to work with these constructs, but at least
the basics are in now.

Chris Lattner a91a563530 Previously, all operands to Constant were themselves constant.
In the new world order, BlockAddress can have a BasicBlock operand.
This doesn't permute much, because if you have a ConstantExpr (or
anything more specific than Constant) we still know the operand has
to be a Constant.
