[ADT] NFC: Generalize GraphTraits requirement of "NodeType *" in interfaces to "NodeRef", and migrate SCCIterator.h to use NodeRef

Summary: By generalize the interface, users are able to inject more flexible Node token into the algorithm, for example, a pair of vector<Node>* and index integer. Currently I only migrated SCCIterator to use NodeRef, but more is coming. It's a NFC.

llvm-svn: 278674

LLVM/Clang 3.8 is directly usable as a cross compiler for CloudABI/i686.
In 3.9rc1 there are a couple of regressions in the driver that cause it
to be less usable:

- PIE was enabled unconditionally, even though it's only available for
  x86-64 and aarch64.
- Some inline assembly fails to build, due to a shortage of registers,
  as frame pointers are not omitted.

Both these changes are fairly low risk (read: they don't affect other
targets), so go ahead and merge them into 3.9, so we can use an
unmodified compiler on all architectures.

[Sema] Fix a crash on variadic enable_if functions.

Currently, when trying to evaluate an enable_if condition, we try to
evaluate all arguments a user passes to a function. Given that we can't
use variadic arguments from said condition anyway, not converting them
is a reasonable thing to do. So, this patch makes us ignore any varargs
when attempting to check an enable_if condition.

We'd crash because, in order to convert an argument, we need its
ParmVarDecl. Variadic arguments don't have ParmVarDecls.

[SCEV] Update interface to handle SCEVExpander insert point motion.

Summary:
This is an extension of the fix in r271424.  That fix dealt with builder
insert points being moved by SCEV expansion, but only for the lifetime
of the expand call.  This change modifies the interface so that LSR can
safely call expand multiple times at the same insert point and do the
right thing if one of the expansions decides to move the original insert
point.

This is a fix for PR28719.

the compile command line, split it up and add the required `-lpthread`
between %libomp-compile and %libomp-run.

Fix false positive in -Wunsequenced and templates.

For builtin logical operators, there is a well-defined ordering of argument
evaluation.  For overloaded operator of the same type, there is no argument
evaluation order, similar to other function calls.  When both are present,
uninstantiated templates with an operator&& is treated as an unresolved
function call.  Unresolved function calls are treated as normal function calls,
and may result in false positives when the builtin logical operator is used.
Have the unsequenced checker ignore dependent expressions to avoid this
false positive.  The check also happens in template instantiations to catch
when the overloaded operator is used.
