Richard Trieu 553b2b2e5d 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)

Douglas Gregor 4f4946aaaa Whenever we complain about a failed initialization of a function or
method parameter, provide a note pointing at the parameter itself so
the user does not have to manually look for the function/method being
called and match up parameters to arguments. For example, we now get:

t.c:4:5: warning: incompatible pointer types passing 'long *' to
parameter of
      type 'int *' [-pedantic]
  f(long_ptr);
    ^~~~~~~~
t.c:1:13: note: passing argument to parameter 'x' here
void f(int *x);
            ^

Douglas Gregor c68e140657 Improve diagnostics when we fail to convert from a source type to a
destination type for initialization, assignment, parameter-passing,
etc. The main issue fixed here is that we used rather confusing
wording for diagnostics such as

t.c:2:9: warning: initializing 'char const [2]' discards qualifiers,
      expected 'char *' [-pedantic]
  char *name = __func__;
        ^      ~~~~~~~~

We're not initializing a 'char const [2]', we're initializing a 'char
*' with an expression of type 'char const [2]'. Similar problems
existed for other diagnostics in this area, so I've normalized them all
with more precise descriptive text to say what we're
initializing/converting/assigning/etc. from and to. The warning for
the code above is now:

t.c:2:9: warning: initializing 'char *' from an expression of type
      'char const [2]' discards qualifiers [-pedantic]
  char *name = __func__;
        ^      ~~~~~~~~

Fixes <rdar://problem/7447179>.

Daniel Dunbar 8fbe78f6fc 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).

Eli Friedman 9e81b02ec5 Don't allow defining a block with a non-prototype type. Remove a
hack which introduces some strange inconsistencies in compatibility 
for block pointers.

Note that unlike an earlier revision proposed on cfe-commits, this patch 
still allows declaring block pointers without a prototype.

Use -fblocks in the various testcases that use blocks.
