John McCall 9dffe6f51c Fix -fno-rtti -fexceptions by forcing the emission of (non-"builtin") RTTI 
when used by the exceptions routines.  Fixes PR 6974.

John McCall 891f80ec2f Teach EHCleanupBlock to deal appropriately with the possibility that there 
might not have been an insertion block set at start.  Fixes PR6975.

John McCall ac41816269 Call PerformCopyInitialization to properly initialize the exception temporary 
in a throw expression.  Use EmitAnyExprToMem to emit the throw expression,
which magically elides the final copy-constructor call (which raises a new
strict-compliance bug, but baby steps).  Give __cxa_throw a destructor pointer
if the exception type has a non-trivial destructor.

John McCall 3d3ec1c099 Miscellaneous codegen cleanups. Mostly, don't create new basic blocks 
just to save the current insertion state!  This change significantly
simplifies the IR CFG in exceptions code.

John McCall 9fc6a77746 More refactoring around constructor/destructor code generation. 
Fix some bugs with function-try-blocks and simplify normal try-block
code generation.

This implementation excludes a deleting destructor's call to
operator delete() from the function-try-block, which I believe
is correct but which I can't find straightforward support for at
a moment's glance.

Daniel Dunbar b2987d159a Switch to using -fsjlj-exceptions instead of hard-coding it. Notably, this fixes 
calls to the UnwindResumeOrRethrow function for C++/Obj-C exception handling,
for Darwin ARM.

John McCall 04a67a6aa3 Standardize the parsing of function type attributes in a way that 
follows (as conservatively as possible) gcc's current behavior:  attributes
written on return types that don't apply there are applied to the function
instead, etc.  Only parse CC attributes as type attributes, not as decl attributes;
don't accepet noreturn as a decl attribute on ValueDecls, either (it still
needs to apply to other decls, like blocks).  Consistently consume CC/noreturn
information throughout codegen;  enforce this by removing their default values
in CodeGenTypes::getFunctionInfo().

Douglas Gregor 154fe9812f There is no such thing as typeinfo for a cv-qualified type. Assert 
that this is true when mangling, then fix up the various places in
Sema and/or CodeGen that need to remove qualifiers. Addresses a
linking issue when building LLVM with Clang.
