Douglas Gregor d6bc5e6bbc When a declaration of a function is missing an exception specification
that was present in a prior declaration, emit a warning rather than a
hard error (which we did before, and still do with mismatched
exception specifications). Moreover, provide a fix-it hint with the
throw() clause that should be added, e.g.,

t.C:10:7: warning: 'operator new' is missing exception specification
      'throw(std::bad_alloc)'
void *operator new(unsigned long sz)
      ^
                                     throw(std::bad_alloc)

As part of this, disable the warning when we're missing an exception
specification on operator new, operator new[], operator delete, or
operator delete[] when exceptions are turned off (-fno-exceptions).

Fixes PR5957.

John McCall 85f9055955 When pretty-printing tag types, only print the tag if we're in C (and
therefore not creating ElaboratedTypes, which are still pretty-printed
with the written tag).

Most of these testcase changes were done by script, so don't feel too
sorry for my fingers.

Eli Friedman 7827520ce8 Initialization improvements: addition of string initialization and a few
small bug fixes in SemaInit, switch over SemaDecl to use it more often, and
change a bunch of diagnostics which are different with the new initialization
code.

Daniel Dunbar 8fbe78f6fc Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- This is designed to make it obvious that %clang_cc1 is a "test variable"
   which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
   can be useful to redefine what gets run as 'clang -cc1' (for example, to set
   a default target).

Sebastian Redl 7eb5d377d7 Use partial diagnostics properly in call to RequireCompleteType. Among other things, this means we get a note on the declaration of the incomplete type when it is used in an exception specification.

Sebastian Redl 4915e63d3b Test exception spec compatibility on return type and parameters.
Along the way, use RequireCompleteType when testing exception spec types.
Separate all the ugly spec stuff into its own file.

Sebastian Redl 5d43164bc2 Implement the core checking for compatible exception specifications in assignment and initialization.
The exception specification of the assignee must be the same or a subset of the target. In addition, exception specifications on arguments and return types must be equivalent, but this is not implemented yet.
This currently produces two diagnostics for every invalid assignment/initialization, due to the diagnostic produced outside PerformImplicitConversion, e.g. in CheckSingleInitializer. I don't know how to suppress this; in any case I think it is the wrong place for a diagnostic, since there are other diagnostics produced inside the function. So I'm leaving it as it is for the moment.
