PR41111, PR5925, PR13210: Teach tentative parsing to annotate identifiers and
nested names as id-expressions, using the annot_primary_expr annotation, where
possible. This removes some redundant lookups, and also allows us to
typo-correct within tentative parsing, and to carry on disambiguating past an
identifier which we can determine will fail lookup as both a type and as a
non-type, allowing us to disambiguate more declarations (and thus offer
improved error recovery for such cases).

This also introduces to the parser the notion of a tentatively-declared name,
which is an identifier which we *might* have seen a declaration for in a
tentative parse (but only if we end up disambiguating the tokens as a
declaration). This is necessary to correctly disambiguate cases where a
variable is used within its own initializer.

Fix a problem in digraph handling where "[:" might be treated as "<::" and

this in the future.

Changes to the name lookup have caused a regression in the digraph fix-it hint.
For instance:

template <class T> void E() {};
class F {};

void test() {
::E<::F>();
E<::F>();
}

Changes to the name lookup have caused a regression in the digraph fix-it hint.
For instance:

template <class T> void E() {};
class F {};

void test() {
::E<::F>();
E<::F>();
}

Gives the following error messages:

error: found '<::' after a template name which forms the
digraph '<:' (aka '[') and a ':', did you mean '< ::'?
::E<::F>();
^~~
< ::
error: expected expression
E<::F>();
^
error: expected ']'
note: to match this '['
E<::F>();

This patch adds the digraph fix-it check right before the name lookup,
moves the shared checking code to a new function, and adds new
tests to catch future regressions.

Update tests to use %clang_cc1 instead of 'clang-cc' or 'clang -cc1'.
- 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).
