LoopVectorizer: Fix a bug in the vectorization of BinaryOperators. The BinaryOperator can be folded to an Undef, and we don't want to set NSW flags to undef vals.

Fix Alias Bug

Use memcpy to do type punning instead of a cast.  A cast or similar
operation through a union breaks strict aliasing rules.

Allow hasProperty() to be called on bundle-internal instructions.

When calling hasProperty() on an instruction inside a bundle, it should
always behave as if IgnoreBundle was passed, and just return properties
for the current instruction.

Only attempt to aggregate bundle properties whan asked about the bundle
header.

The assertion fires on existing ARM test cases without this fix.

TableGen: Keep track of superclass reference ranges.

def foo : bar;
          ~~~

This allows us to produce more precise diagnostics about a certain
superclass, and even provide fixits.

Add basic fix-its to SMDiagnostic.

Like Clang's FixItHint, SMFixIt represents an insertion, replacement, or
removal of source text. One or more fix-its can be emitted as part of
a diagnostic, and will be printed below the source range line to show the
user how they can fix their code.

Currently, the only client of SMFixIt is clang-tblgen; thus, the tests for
this behavior live in clang/test/TableGen/tg-fixits.td. If/when SMFixIt is
adopted within LLVM itself, those tests should be moved to the LLVM suite.

remove the rest of the "written by" lines in the documentation.  It is
against the developer policy to include this sort of thing as SVN blame
already captures this in a far more fine-grained way.

Teach InstCombine to hoist FABS and FNEG through FPTRUNC instructions.  The application of these operations commutes with the truncation, so we should prefer to do them in the smallest size we can, to save register space, use smaller constant pool entries, etc.
