diagnostic message are compared. If either is a substring of the other, then
no error is given. This gives rise to an unexpected case:
// expect-error{{candidate function has different number of parameters}}
will match the following error messages from Clang:
candidate function has different number of parameters (expected 1 but has 2)
candidate function has different number of parameters
It will also match these other error messages:
candidate function
function has different number of parameters
number of parameters
This patch will change so that the verification string must be a substring of
the diagnostic message before accepting. Also, all the failing tests from this
change have been corrected. Some stats from this cleanup:
87 - removed extra spaces around verification strings
70 - wording updates to diagnostics
40 - extra leading or trailing characters (typos, unmatched parens or quotes)
35 - diagnostic level was included (error:, warning:, or note:)
18 - flag name put in the warning (-Wprotocol)

LookupInObjCMethod. Doing so allows all sorts of invalid code
to slip through to codegen. This patch does not change the
AST representation of super, though that would now be a natural
thing to do since it can only be in the receiver position and
in the base of a ObjCPropertyRefExpr.
There are still several ugly areas handling super in the parser,
but this is definitely a step in the right direction.

- This is designed to make it obvious that %clang_cc1 is a "test variable"
which is substituted. It is '%clang_cc1' instead of '%clang -cc1' because it
can be useful to redefine what gets run as 'clang -cc1' (for example, to set
a default target).

This allow us to document a simple migration path...change "Class <foo>" to "id <foo>".
This effects:
- <rdar://problem/6761939> TASK: File source change radars for "qualified Class" errors
- <rdar://problem/6761864> Protocol qualified Class is unsupported

This will simplify clang adoption, and is probably better "etiquette" (since gcc has always accepted this idiom without warning). Once we are over the adoption hurdle, we can turn this into an error.

- Disallow casting 'super'. GCC allows this, however it doesn't make sense (super isn't an expression and the cast won't alter lookup/dispatch).
- Tighten up lookup when messaging 'self'.
