Fixed another assert exposed by fuzzing.  The utility function getRegisterEnum()
was asserting because the (RegClass, RegNum) combination doesn't make sense from
an encoding point of view.

Since getRegisterEnum() is used all over the place, to change the code to check
for encoding error after each call would not only bloat the code, but also make
it less readable.  An Err flag is added to the ARMBasicMCBuilder where a client
can set a non-zero value to indicate some kind of error condition while building
up the MCInst.  ARMBasicMCBuilder::BuildIt() checks this flag and returns false
if a non-zero value is detected.

Teach postra machine licm to hoist more obvious invariants, e.g. instructions with no source operands.

Eliminate MachineBasicBlock::const_livein_iterator and make
MachineBasicBlock::livein_iterator a const_iterator, because
clients shouldn't ever be using the iterator interface to
mutate the livein set.

Rename MachineFrameInfo variables to MFI, for consistency with
the rest of CodeGen.

Move MachineRegisterInfo's isLiveIn and isLiveOut out of line.

Use MachineBasicBlock::isLiveIn.

Delete an unused member variable.

Teach ScalarEvolution to simplify smax and umax when it can prove
that one operand is always greater than another.

Actually... return after the check for invalid input.

BumpPtrAllocator::Reset() doesn't need to allocate anything. (Thanks, Jakob)

Update unittest for allocator laziness.

Let BumpPtrAllocator lazily allocate the first slab.

We have some code in llvm and clang where a BumpPtrAllocator is declared in a
class but never used in the common case. Stop wasting memory there.

Remove SCCVN from the CMake build system.

SCCVN, we hardly knew ye!

Fix PR6826: GraphWriter delete the generated file before "dotty" load it,
patch by 'ether'.

Replace r101053 with a fix for getSOImmValRotate() so that it will correctly
recognize all the valid rotated immediates.  This fixes the disassembler
issue and will also help codegen for some unusual constant values.

Teach IndVarSimplify how to eliminate remainder operators where the
numerator is an induction variable. For example, with code like this:

  for (i=0;i<n;++i)
    x[i%n] = 0;

IndVarSimplify will now recognize that i is always less than n inside
the loop, and eliminate the remainder.

VMCore: Add Type::getIntN[Ptr]Ty, which are the obvious generic forms of
Type::getInt{1,8,...}[Ptr]Ty, so code can consistently use the methods on Type
without occasionally needed to call IntegerType::get.

IRBuilder: Add Create{Shl,LShr,And,Or,Xor} methods from uin64_t and APInt constants.

Build system fix to make llvm-mc properly build
after edis.  Really, there ought to be some
mechanism to ensure that PARALLEL_DIRS get built
after DIRS.
