Unrevert r166268, reverted in r166272, with a fix for the issue which Nick
found: if an overloaded operator& is present before a template definition,
the expression &T::foo is represented as a CXXOperatorCallExpr, not as a
UnaryOperator, so we didn't notice that it's permitted to reference a non-static
data member of an unrelated class.
While investigating this, I discovered another problem in this area: we are
treating template default arguments as unevaluated contexts during substitution,
resulting in performing incorrect checks for uses of non-static data members in
C++11. That is not fixed by this patch (I'll look into this soon; it's related
to the failure to correctly instantiate constexpr function templates), but was
resulting in this bug not firing in C++11 mode (except with -Wc++98-compat).

This patch is to fix radar://8426430. It is about llvm support of __builtin_debugtrap()
which is supposed to consistently raise SIGTRAP across all systems. In contrast,
__builtin_trap() behave differently on different systems. e.g. it raises SIGTRAP on ARM, and
SIGILL on X86. The purpose of __builtin_debugtrap() is to consistently provide "trap"
functionality, in the mean time preserve the compatibility with on gcc on __builtin_trap().
The X86 backend is already able to handle debugtrap(). This patch is to:
1) make front-end recognize "__builtin_debugtrap()" (emboddied in the one-line change to Clang).
2) In DAG legalization phase, by default, "debugtrap" will be replaced with "trap", which
make the __builtin_debugtrap() "available" to all existing ports without the hassle of
changing their code.
3) If trap-function is specified (via -trap-func=xyz to llc), both __builtin_debugtrap() and
__builtin_trap() will be expanded into the function call of the specified trap function.
This behavior may need change in the future.
The provided testing-case is to make sure 2) and 3) are working for ARM port, and we
already have a testing case for x86.

Added the infrastructure necessary for plug-ins to be able to add their own settings instead of having settings added to existing ones. In particular "target.disable-kext-loading" was added to "target" where it should actually be specific to the the dynamic loader plugin. Now the plug-in manager has the ability to create settings at the root level starting with "plugin". Each plug-in type can add new sub dictionaries, and then each plug-in can register a setting dictionary under its own short name. For example the DynamicLoaderDarwinKernel plug-in now registers a setting dictionary at:
plugin
dynamic-loader
macosx-kernel
(bool) disable-kext-loading
To settings can be set using:
(lldb) settings set plugin.dynamic-loader.macosx-kernel.disable-kext-loading true

Allow objc_requires_super to be used to check class methods as well.
Also, unify ObjCShouldCallSuperDealloc and ObjCShouldCallSuperFinalize.
The two have identical behavior and will never be active at the same time.
There's one last simplification now, which is that if we see a call to
[super foo] and we are currently in a method named 'foo', we will
/unconditionally/ clear the ObjCShouldCallSuper flag, rather than check
first to see if we're in a method where calling super is required. There's
no reason to pay the extra lookup price here.

Change VerifyDiagnosticConsumer so that it *must* contain at least one "expected-*" directive. As a result, for test-cases that are not expected to generate any diagnostics, an additional directive "expected-no-diagnostics" has been implemented which can then be included in such test-cases. This new directive may not be used in conjunction with any other "expected-*" directive.
This change was initially proposed as a solution to the problem highlighted by check-in r164677, i.e. that -verify will not cause a test-case failure where the compile command does not actually reference the file.

Fix directive parsing in VerifyDiagnosticConsumer so that it ensures that "expected" is at the start of the word and will no longer accept typos such as "junkexpected-*" as a valid "expected-*" directive. A very few test-cases had to be amended to adhere to the new rule.
