Douglas Gregor 91c25eadea Whenever we have a BalancedDelimiterTracker, we have a 'nested' scope
where '>' is going to behave as an operator (and not as a '>' closing
a template argument list).

John McCall 6347b68fd9 Change how we suppress access control in explicit instantiations
so that we actually accumulate all the delayed diagnostics.  Do
this so that we can restore those diagnostics to good standing
if it turns out that we were wrong to suppress, e.g. if the
tag specifier is actually an elaborated type specifier and not
a declaration.

John McCall 2ec85375eb Refactor DelayedDiagnostics so that it keeps diagnostics in
separate pools owned by the RAII objects that keep pushing
decl state.  This gives us quite a bit more flexibility.

Douglas Gregor e9bba4f1a4 Implement bracket insertion for Objective-C instance message sends as
part of parser recovery. For example, given:

  a method1:arg];

we detect after parsing the expression "a" that we have the start of a
message send expression. We pretend we've seen a '[' prior to the a,
then parse the remainder as a message send. We'll then give a
diagnostic+fix-it such as:

fixit-objc-message.m:17:3: error: missing '[' at start of message
      send expression
  a method1:arg];
  ^
  [

The algorithm here is very simple, and always assumes that the open
bracket goes at the beginning of the message send. It also only works
for non-super instance message sends at this time.

Argyrios Kyrtzidis 355094ef06 Make sure parens/braces/brackets are correctly balanced.
In a line like:

(;

the semicolon leaves Parser:ParenCount unbalanced (it's 1 even though we stopped looking for a right paren).
This may affect later parsing and result in bad recovery for parsing errors.

Chris Lattner 3c674cf804 If we enter parens, colons can become un-sacred, allowing us to emit
a better diagnostic in the second example.

Chris Lattner 5701386620 move GreaterThanIsOperatorScope into RAIIObjectsForParser. Add some more
TODOs for other classes that could be moved out of Parser.h.  I don't plan
to do these in the near term though.

Chris Lattner d5c1c9d0ae refactor the 'ColonIsSacred' argument to ParseOptionalCXXScopeSpecifier
to be a bool in Parser that is twiddled by the ColonProtectionRAIIObject
class.  No functionality change.
