Richard Smith 0576681bac 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.

Richard Trieu c11030ea93 Fix a problem in digraph handling where "[:" might be treated as "<::" and
erronously trigger the digraph correction fix-it.  Include a new test to catch
this in the future.

Richard Trieu 950be71c74 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.

Richard Smith ea698b3f6c Detect when the string "<::" is found in code after a cast or template name and is interpreted as "[:" because of the digraph "<:". When found, give an error with a fix-it to add whitespace between the "<" and "::".
Patch by Richard Trieu! Plus a small tweak from me to deal with one of the tokens coming from a macro.

Daniel Dunbar a5728872c7 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).
