8dffc819c5 Model the carry bit on ppc32. Without this we could
move a SUBFC (etc.) below the SUBFE (etc.) that consumed
the carry bit.  Add missing ADDIC8, noticed along the way.

e220c4b3d9 Add support for using the FLAGS result of or, xor, and and instructions
on x86, to avoid explicit test instructions. A few existing tests changed
due to arbitrary register allocation differences.

88d9839d07 Update malloc call creation code (AllocType is now the element type of the malloc, not the resulting type).
In getMallocArraySize(), fix bug in the case that array size is the product of 2 constants.

Extend isArrayMalloc() and getMallocArraySize() to handle case where malloc is used as char array.

Ensure that ArraySize in LowerAllocations::runOnBasicBlock() is correct type.

Extend Instruction::isSafeToSpeculativelyExecute() to handle malloc calls.

Add verification for malloc calls.

Reviewed by Dan Gohman.

f8a56255a5 Fix a bug in sdisel switch lowering code. When it updates the phi nodes in switch successor blocks, it can introduce multiple phi operands of the same value from different blocks (and may not be on the predecessor list).
This can be seen on CodeGen/Generic/2006-09-06-SwitchLowering.ll. But it's not known to cause any real regression (but I have added an assertion for it now).

6f65d79750 Add a new pass for doing late hoisting of floating-point and vector
constants out of loops. These aren't covered by the regular LICM
pass, because in LLVM IR constants don't require separate
instructions. They're not always covered by the MachineLICM pass
either, because it doesn't know how to unfold folded constant-pool
loads. This is somewhat experimental at this point, and off by
default.
