Removing some unneeded code, and a diagnostic that was obsoleted. The type has already been determined to be a ValueDecl by virtue of the attribute subjects.

Added some test case coverage as well.

No need for the manual quotes and extra getName() call. No functional changes intended.

This diagnostic did not accept arguments, and did not have any test coverage. Parameterized the diagnostic, and made it more consistent with other attribute diagnostic wordings. Added test coverage.

Since this warning was generalized, it was also given a sensible warning group flag and the corresponding test was updated to reflect this.

Removed a string literal for an attribute name, which means the attribute name will be quoted in the diagnostic. Manually added some quotes to a diagnostic for consistency. Updated the test cases as appropriate.

Teach the diagnostics engine about the Attr type to make reporting on semantic attributes easier (and not require hard-coded strings). This requires a getSpelling() function on the Attr class, which is table-driven. Updates a handful of cases where a hard-coded string was being used to test the functionality out. Updating associated test cases for the improved quoting.

[ms-abi] Fixes improperly sized vfptrs with pragma pack

With pragma pack, the layout engine would produce vfptrs that were 
packed width rather than pointer width.  This patch addresses the issue 
and adds a test case.

Warn on mismatched parentheses in memcmp and friends.

Thisadds a new warning that warns on code like this:

  if (memcmp(a, b, sizeof(a) != 0))

The warning looks like:

test4.cc:5:30: warning: size argument in 'memcmp' call is a comparison [-Wmemsize-comparison]
  if (memcmp(a, b, sizeof(a) != 0))
                   ~~~~~~~~~~^~~~
test4.cc:5:7: note: did you mean to compare the result of 'memcmp' instead?
  if (memcmp(a, b, sizeof(a) != 0))
      ^                          ~
                            )
test4.cc:5:20: note: explicitly cast the argument to size_t to silence this warning
  if (memcmp(a, b, sizeof(a) != 0))
                   ^
                   (size_t)(     )
1 warning generated.

This found 2 bugs in chromium and has 0 false positives on both chromium and
llvm.

The idea of triggering this warning on a binop in the size argument is due to
rnk.
