Comment lexer: counting backwards from token end is thought to be confusing.  We already have a pointer to the beginning of the token, so use it to extract the text instead.

Remove unsigned and a pointer from a comment token (so that each token can have only one semantic string value attached to it), at a cost of adding an additional token.

Implement John McCall's review of r159212 other than the this pointer not
being updated. Will fix that in a second.

patch to suggest 'static' function should be 'static inline' 
when it appears to be unused and occurs in a header.

Check for non-POD vararg argument type after default argument promotion, not
before, so we don't incorrectly think arguments of function type are non-POD.

Refactoring after r159290: don't hold onto and check a misleading QualType.

objective-c mrc: Issue warning for mrc, as is done for arc, when
property retains a block object as it could be on

Fix an infinite loop in comment lexer: we were not advancing in the input character stream when we saw a '<' that is not a start of an HTML tag.

Attaching documentation comments to declarations: don't attach a comment to a declaration if there is a preprocessor directive between them.

Fix uninitialized variable use bug found by the clairvoyant static analyzer.

Commit::canReplaceText would not initialize its out 'Len' parameter before
returning true and it would be used uninitialized in Commit::replaceText.

Cleanup \brief comment.  Since it is a single paragraph, no need to save newlines there.

Fix another issue with devirtualizing calls to final methods by passing them
the correct this pointer. There is some potential for sharing a bit more
code with canDevirtualizeMemberFunctionCalls, but that can be done in an
independent patch.

Add warning flag -Winvalid-pp-token for preprocessing-tokens which have
undefined behaviour, and move the diagnostic for '' from an Error into
an ExtWarn in this group. This is important for some users of the preprocessor,
and is necessary for gcc compatibility.
