Fix parsing of trailing-return-type. Types are syntactically prohibited from
being defined here: [] () -> struct S {} does not define struct S.

In passing, implement DR1318 (syntactic disambiguation of 'final').

Disambiguate between C++11 lambda expressions and C99 array
designators in the parser. In the worst case, this disambiguation
requires tentative parsing just past the closing ']', but for most
cases we'll be able to tell by looking ahead just one token (without
going into the heavyweight tentative parsing machinery).

Improve recovery for lambda expressions that have 'mutable' or a
trailing return type but not a '()'. Recover by inserting the
parentheses. Thanks to Xeo on IRC for the example.

Remove the "unsupported" error for lambda expressions. It's annoying,
and rapidly becoming untrue.

Stub out the Sema interface for lambda expressions, and change the parser to use it. Unconditionally error on lambda expressions because they don't work in any meaningful way yet.

Modify how the -verify flag works. Currently, the verification string and
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)
