Make sure the context and type fields are MDNodes. We will generate
verification errors if those fields are non-empty strings.
Fix testing cases to make them pass the verifier.

The language reference says that:

"If a symbol appears in the @llvm.used list, then the compiler,
assembler, and linker are required to treat the symbol as if there is
a reference to the symbol that it cannot see"

Since even the linker cannot see the reference, we must assume that
the reference can be using the symbol table. For example, a user can add
__attribute__((used)) to a debug helper function like dump and use it from
a debugger.

String operations resulted by raw_string_ostream in the INVALID macro can lead
to significant compile-time overhead when compiling large size source code.
This is because raw_string_ostream relies on TypeFinder class, whose
compile-time cost increases as the size of the module increases. This patch
targets to ensure that it only track detection failures if actually needed.
In this way, we can avoid expensive string operations in normal execution.

With this patch file, the relative compile-time cost of Polly-detect pass does
not increase even when compiling very large size source code.

BalancedDelimiterTracker::diagnoseOverflow calls P.SkipUntil, and before this
patch P.SkipUnti is recursive, causing problems on systems with small stacks.
This patch fixes it by making P.SkipUnti non recursive when just looking for
eof.

Handle the case where we are stepping through code with no symbols, so we can't really find the function start PC 
and so the StackID changes with every step.  Do so by checking the parent frame ID, and if it hasn't changed,
then we haven't stepped in.

There's no need to specify a flag to omit frame pointer elimination on non-leaf
nodes...(Honestly, I can't parse that option out.) Use the function attribute
stuff instead.

It's still not as simple as it should be because of the many duplicated

The /include command line option is equivalent to Unix --undefined
option, which forces the linker to resolve the given symbol name
as if it's an unresolved symbol in one of its input files. This feature
is used to link an additional object file or a shared library that no
input files refer to.

Fix test suite make so that -std=c++11 gets set properly for supported compilers and -std=c++0x gets set only for gcc 4.6 versions. Previously, -std=c++0x was being set for all compilers.

r186899 and r187061 added a preferred way for some architectures not to get
intrinsic generation for math builtins. So the code changes in r185568 can
now be undone (the test remains).

Prior to this patch, IfConverter may widen the cases where a sequence of
instructions were executed because of the way it uses nested predicates. This
result in incorrect execution.

For instance, Let A be a basic block that flows conditionally into B and B be a
predicated block.
B can be predicated with A.BrToBPredicate into A iff B.Predicate is less
"permissive" than A.BrToBPredicate, i.e., iff A.BrToBPredicate subsumes
B.Predicate.

The IfConverter was checking the opposite: B.Predicate subsumes
A.BrToBPredicate.
