When a '>>' token is split into two '>' tokens (in C++11 onwards), or (as an
extension) when we do the same for other tokens starting with a '>', we can't
just use a location pointing to the first '>' as the location of the split
token, because that would result in our miscomputing the length and spelling
for the token. As a consequence, for example, a refactoring replacing 'A<X>'
with something else would sometimes replace one character too many, and
similarly diagnostics highlighting a template-id source range would highlight
one character too many.
Fix this by creating an expansion range covering the first character of the
'>>' token, whose spelling is '>'. For this to work, we generalize the
expansion range of a macro FileID to be either a token range (the common case)
or a character range (used in this new case).

syntax unless we have a reason to think otherwise.
This improves error recovery in a couple of cases.

We were incorrectly setting PrevTokLocation to the first token in the
annotation token instead of the last when consuming it. To fix this without
adding a complex switch to the hot path through ConsumeToken, we now have a
ConsumeAnnotationToken function for consuming annotation tokens in addition
to the other Consume*Token special case functions.

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).

allow this, and we should warn on it, but it turns out that people were already
relying on this.
We should introduce a -Wgcc-compat warning for this if the attributes are known
to GCC, but we don't currently track enough information about attributes to do
so reliably.

member-declaration. In the process, fix a couple of bugs that had crept in
where we would parse the first and subsequent member-declarators differently
(in particular, we didn't accept an asm-label on a member function definition
within a class, and we would accept virt-specifiers and attributes in the wrong
order on the first declarator but not on subsequent ones).

C++1y, so stop adding the 'const' there. Provide a compatibility warning for
code relying on this in C++11, with a fix-it hint. Update our lazily-written
tests to add the const, except for those ones which were testing our
implementation of this rule.

there. Keep it in -Wextra-semi, though, since it's still questionable.

instead of a semicolon (as sometimes happens during refactorings). When such a
comma is seen at the end of a line, and is followed by something which can't
possibly be a declarator (or even something which might be a plausible typo for
a declarator), suggest that a semicolon was intended.
