sys::fs::make_absolute was turning '.' into '<path>/.' which broke prefix
comparison logic. Stripping these extra chars fixes the problem.

CGCleanup.h isn't meant to be included by all of CodeGen according to

The type <3 x i8> is a common in graphics and we want to be able to vectorize it.

This changes accelerates bullet by 12% and 471_omnetpp by 5%.

This is in preparation for the backwards references to bound
nodes, which will expose a lot more about how matches occur.  Main
changes:
- instead of building the tree of bound nodes, we build a "set" of bound
  nodes and explode all possible match combinations while running
  through the matchers; this will allow us to also implement matchers
  that filter down the current set of matches, like "equalsBoundNode"
- take the set of bound nodes at the start of the match into
  consideration when doing memoization; as part of that, reevaluated
  that memoization gives us benefits that are large enough (it still
  does - the effect on common match patterns is up to an order of
  magnitude)
- reset the bound nodes when a node does not match, thus never leaking
  information from partial sub-matcher matches for failing matchers

Effects:
- we can now correctly "explode" combinatorial matches, for example:
  allOf(forEachDescendant(...bind("a")),
  forEachDescendant(...bind("b"))) will now trigger matches for all
  combinations of matching "a" and "b"s.
- we now never expose bound nodes from partial matches in matchers that
  did not match in the end - this fixes a long-standing issue

FIXMEs:
- rename BoundNodesTreeBuilder to BoundNodesBuilder or
  BoundNodesSetBuilder, as we don't build a tree any more; this is out
  of scope for this change, though
- we're seeing some performance regressions (around 10%), but I expect
  some performance tuning will get that back, and it's easily worth
  the increase in expressiveness for now

In Itanium, dynamic classes have one vtable with several different
address points for dynamic base classes that can't share vtables.

In the MS C++ ABI, each vbtable that can't be shared gets its own
symbol, similar to how ctor vtables work in Itanium.  However, instead
of mangling the subobject offset into the symbol, the unique portions of
the inheritance path are mangled into the symbol to make it unique.

This patch implements the MSVC 2012 scheme for forming unique vbtable
symbol names.  MSVC 2010 use the same mangling with a different subset
of the path.  Implementing that mangling and possibly others is TODO.

Each vbtable is an array of i32 offsets from the vbptr that points to it
to another virtual base subobject.  The first entry of a vbtable always
points to the base of the current subobject, implying that it is the
same no matter which parent class contains it.

gcc's inputs are already added by the InputInfoList passed to
Action::ConstructJob.

Fixes a regression from r183989.  This was manifesting when targetting
mingw as an extra input argument to gcc when assembling.  It presumably
affects other situations where clang calls gcc.

Prior to r183989, forwardToGCC() was returning false because the INPUT
option defined in OptParser.td had the DriverOption flag set on it.
LLVM's Option library does not set this flag for INPUT.

Revert r184302 on Renato's behalf - it broke the bots and he's asked me to revert as he's unavailable.

For now, it is only done with DEBUGMAKE is provided. That makes
things harder to debug during ports of compiler-rt on other systems.

The RenderMethod field in RegisterOperand class sets the name of the method on the target specific operand to call to add the target specific operand to an MCInst. This patch defines RenderMethod for mips RegisterOperand classes and removes redundant code from MipsAsmParser.cpp

linux/if_ppp.h is broken in certain kernels.

Summary:
When processing a call to a function, which got passed less arguments than it
expects, the analyzer would crash.

I've also added a test for that and a analyzer warning which detects these
cases.
