wrapper returns a vector of integers when passed a vector of pointers) by having
getIntPtrType itself return a vector of integers in this case. Outside of this
wrapper, I didn't find anywhere in the codebase that was relying on the old
behaviour for vectors of pointers, so give this a whirl through the buildbots.

We may need to change the way profile counter values are stored, but
saturation is the wrong thing to do. Just remove it for now.

Add getCostXXX calls for different families of opcodes, such as casts, arithmetic, cmp, etc.
Port the LoopVectorizer to the new API.
The LoopVectorizer now finds instructions which will remain uniform after vectorization. It uses this information when calculating the cost of these instructions.

It was unmaintained and not much more than a stub. The new DependenceAnalysis
pass is both more general and complete.

APInt::shl generated llvm.trap to guard against shifts greater than bit-width.
This was already checked with an assert, and there was a special case for
shifts equal to bit-width. Modify this check to catch shifts greater than or
equal to bit-width, so llvm.trap isn't generated.

list of externals. This makes sense since a shared library with no symbols
can still be useful if it has static constructors.

Enabled with -verify-scev. This could be extended significantly but hopefully
catches the common cases now. Note that it's not enabled by default in any
configuration because the way it tries to distinguish SCEVs is still fragile and
may produce false positives. Also the test-suite isn't clean yet, one example
is that it fails if a pass drops an NSW bit but it's still present in SCEV's
cached. Cleaning up all those cases will take some time.

As discussed on IRC, add VectorTargetTransform::getNumberOfParts
to provide a stable interface to the vector legalization splitting factor.

include/llvm/MC/MCTargetAsmParser.h:46:8: error: 'llvm::ParseInstructionInfo' has a field 'llvm::ParseInstructionInfo::AsmRewrites' whose type uses the anonymous namespace [-Werror]

Most places can use PrintFatalError as the unwinding mechanism was not
used for anything other than printing the error. The single exception
was CodeGenDAGPatterns.cpp, where intermediate errors during type
resolution were ignored to simplify incremental platform development.
This use is replaced by an error flag in TreePattern and bailout earlier
in various places if it is set.

Relationship maps are represented as InstrMapping records which are parsed by
TableGen and the information is used to construct mapping tables to represent
appropriate relations between instructions. These tables are emitted into
XXXGenInstrInfo.inc file along with the functions to query them.

This patch adds initial PPC64 TOC MC object creation using the small mcmodel
(a single 64K TOC) adding the some TOC relocations (R_PPC64_TOC,
R_PPC64_TOC16, and R_PPC64_TOC16DS).
The addition of 'undefinedExplicitRelSym' hook on 'MCELFObjectTargetWriter'
is meant to avoid the creation of an unreferenced ".TOC." symbol (used in
the .odp creation) as well to set the R_PPC64_TOC relocation target as the
temporary ".TOC." symbol. On PPC64 ABI, the R_PPC64_TOC relocation should
not point to any symbol.

a bunch of errors for all the Operator subclasses such as:
include/llvm/Operator.h:76:7: error: deleted function 'virtual llvm::OverflowingBinaryOperator::~OverflowingBinaryOperator()'
include/llvm/Operator.h:43:3: error: overriding non-deleted function 'virtual llvm::Operator::~Operator()'
include/llvm/Operator.h:76:7: error: 'virtual llvm::OverflowingBinaryOperator::~OverflowingBinaryOperator()' is implicitly deleted because the default definition would be ill-formed:
include/llvm/Operator.h:43:3: error: 'virtual llvm::Operator::~Operator()' is private
include/llvm/Operator.h:76:7: error: within this context

called. Provide an (asserting) definition of Operator's private destructor.
Remove destructors from all classes derived from Operator. We don't need them
for safety, because their implicit definitions would be ill-formed (they'd call
Operator's private destructor), and we don't need them to avoid emitting
vtables, because we don't do anything with Operator subclasses which would
trigger vtable instantiation.
The Operator hierarchy is still a complete disaster with regard to undefined
behavior, but this at least allows LLVM to link when using Clang's
-fcatch-undefined-behavior with a new vptr-based type checking mechanism.

and easier to read by adding a couple helper functions. Suggestion by
Chandler Carruth and seconded by Meador Inge!
