Richard Smith 0b350b9ec5 PR21367: Don't accept rvalue references as an extension in C++98 mode if we're in a new-type-id or conversion-type-id, since those things can legitimately be followed by a binary && operator.

Alexander Potapenko e2e8b0e009 Revert r218925 - "Patch to warn if 'override' is missing" 
This CL has caused bootstrap failures on Linux and OSX buildbots running with -Werror.

Example report from http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux/builds/13183/steps/bootstrap%20clang/logs/stdio:

Fariborz Jahanian b91c5d6a79 Patch to warn if 'override' is missing 
for an overriding method if class has at least one
'override' specified on one of its methods.
Reviewed by Doug Gregor. rdar://18295240
(I have already checked in all llvm files with missing 'override'
 methods and Bob Wilson has fixed a TableGen of FastISel so
 no warnings are expected from build of llvm after this patch.
 I have already verified this).

Richard Smith fb8b7b9a1c PR17567: Improve diagnostic for a mistyped constructor name. If we see something 
that looks like a function declaration, except that it's missing a return type,
try typo-correcting it to the relevant constructor name.

In passing, fix a bug where the missing-type-specifier recovery codepath would
drop a preceding scope specifier on the floor, leading to follow-on diagnostics
and incorrect recovery for the auto-in-c++98 hack.

Richard Smith e434590bd9 Change the diagnostics which said 'accepted as an extension' to instead say 
'is an extension'. The former is inappropriate and confusing when building with
-Werror/-pedantic-errors.

Douglas Gregor 205d044552 Switch diagnostic text from "C++0x" over to "C++11". 
We'd also like for "C++11" or "c++11" to be used for the warning
groups, but without removing the old warning flags. Patches welcome;
I've run out of time to work on this today.

Douglas Gregor a52713096d Improve the extension warning for the use of ref-qualifiers, to 
distinguish them from rvalue references. Using the rvalue-references
warning was weird when the ref-qualifier was '&'.
