of "object type" rather than the C definition of "object type". The
difference is that C's "object type" excludes incomplete types such as

  struct X;

However, C's definition also makes it far too easy to use isObjectType
as a means to detect incomplete types when in fact we should use other
means (e.g., Sema::RequireCompleteType) that cope with C++ semantics,
including template instantiation.

I've already audited every use of isObjectType and isIncompleteType to
ensure that they are doing the right thing for both C and C++, so this
is patch does not change any functionality.

 - Don't default to using clang for C++ (use -ccc-clang-cxx to
   override).

 - Default to only using clang on i386 and x86_64 (use
   -ccc-clang-archs "" to override).

 - <rdar://problem/6712350> [driver] clang should not be used on
   powerpc by default
 - <rdar://problem/6705767> driver should default to -ccc-no-clang-cxx

I plan to add a warning that we are not using the clang compiler for
the given compilation so that users do not think clang is being used
in situations it isn't.

This change is motivated by the desire to be able to drop clang into a
build and have things "just work", even if it happens to get used to
compile C++ code or code for an architecture we don't support yet.

1. Make instcombine always canonicalize trunc x to i1 into an icmp(x&1).  This 
   exposes the AND to other instcombine xforms and is more of what the code
   generator expects.
2. Rewrite the remaining trunc pattern match to use 'match', which 
   simplifies it a lot.
