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).

Aaron Ballman 5d153e3133 Diagnose GNU-style attributes preceding virt-specifiers, but only when the attribute is known to GCC. Clang accepts attributes in this position, but
GCC does not, so this is a GCC-compat warning. If the attribute is not known to GCC, then the diagnostic is suppressed.

Aaron Ballman 08b065909f Disallowing GNU-style attributes in new expressions, since they are prohibited by GCC as well.
