Fix parsing of type-specifier-seq's. Types are syntactically allowed to be

new struct S {};
is always ill-formed, even if there is a struct S in scope.
We also had a couple of bugs in ParseOptionalTypeSpecifier caused by it being
under-loved (due to it only being used in a few places) so merge it into
ParseDeclarationSpecifiers with a new DeclSpecContext. To avoid regressing, this
required improving ParseDeclarationSpecifiers' diagnostics in some cases. This
also required teaching ParseSpecifierQualifierList about constexpr... which
incidentally fixes an issue where we'd allow the constexpr specifier in other
bad places.

Make parsing of objc @implementations more robust.
...
Parsing of @implementations was based on modifying global state from
the parser; the logic for late parsing of methods was spread in multiple places
making it difficult to have a robust error recovery.
-it was difficult to ensure that we don't neglect parsing the lexed methods.
-it was difficult to setup the original objc container context for parsing the lexed methods
after completing ParseObjCAtImplementationDeclaration and returning to top level context.
Enhance parsing of @implementations by centralizing it in Parser::ParseObjCAtImplementationDeclaration().
ParseObjCAtImplementationDeclaration now returns only after an @implementation is fully parsed;
all the data and logic for late parsing of methods is now in one place.
This allows us to provide code-completion for late parsed methods with mis-matched braces.

Clang has existing support for debuggers that
...
want to provide "po"-like functionality which
treats the result of an expression implicitly as
"id" (if it is not otherwise known) and prints
it as an Objective-C object.
This has in the past been gated by the
"DebuggerSupport" language option, but that is
too general. Debuggers also provide other commands
like "print" that do not make any assumptions
about whether the object is an Objective-C object.
This patch makes the assumption conditional on a
new language option: DebuggerCastResultToId. I
have also made corresponding modifications to the
testsuite.

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)
