fix PR12075, a regression in a recent transform I added.  In unreachable code, gep chains can be infinite.  Just like "stripPointerCasts", use a set to keep track of visited instructions so we don't recurse infinitely.

agreed on IRC, any remaining issues are best dealt with as bugs.

We have no __has_feature check for this; please shout if you'd like one. This
feature seems too small to be worth its own release notes bullet (again, please
shout if you disagree).

This is necessary to support the existing ppc lowering code for indirect calls.
Fixes PR12071.

  - Make sure that the block expression is instantiation-dependent if the
    block is in a dependent context
  - Make sure that the C++ 'this' expression gets captured even if we
  don't rebuild the AST node during template instantiation. This would
  also have manifested as a bug for lambdas.

This most likely caused us to skip a bunch of code when analyzing with

that provides the behavior of the C++11 library trait
std::is_trivially_constructible<T, Args...>, which can't be
implemented purely as a library.

Since __is_trivially_constructible can have zero or more arguments, I
needed to add Yet Another Type Trait Expression Class, this one
handling arbitrary arguments. The next step will be to migrate
UnaryTypeTrait and BinaryTypeTrait over to this new, more general
TypeTrait class.

Reapply r151317, but when computing the PathDiagnostic profile and size keep into account the nested structure.  Also fix a problem with how
inlining impacted Plist diagnostics, and adjust some ranges in the Plist output due to richer information.

Add support for a missed case when the symbols in a difference

will fill out either a SBLaunchInfo or SBAttachInfo class, then call:

SBProcess SBTarget::Launch (SBLaunchInfo &, SBError &);
SBProcess SBTarget::Attach (SBAttachInfo &, SBError &);

The attach is working right now and allows the ability to set many filters such
as the parent process ID, the user/group ID, the effective user/group ID, and much
more.

The launch is not yet working, but I will get this working soon. By changing our
launch and attach calls to take an object, it allows us to add more capabilities to
launching and attaching without having to have launch and attach functions that
take more and more arguments. 

Once this is all working we will deprecated the older launch and attach fucntions
and eventually remove them.
