Aaron Ballman 86b5eabfea Allow parameter names to be elided in a function definition in C.
WG14 has adopted N2480 (http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2480.pdf)
into C2x at the meetings last week, allowing parameter names of a function
definition to be elided. This patch relaxes the error so that C++ and C2x do not
diagnose this situation, and modes before C2x will allow it as an extension.

This also adds the same feature to ObjC blocks under the assumption that ObjC
wishes to follow the C standard in this regard.

Richard Smith 74639b1900 When a type-id is unexpectedly given a name, assume that the name is unrelated
syntax unless we have a reason to think otherwise.

This improves error recovery in a couple of cases.

Reid Kleckner 88709c6952 Add a test case for blocks taking an array typedef
r183614 was failing because va_list on some platforms is defined in a
similar manner.  This test fails on Windows with r183614 applied.

John McCall 92d627e1b0 Fix an error with the declaration of block parameters that depend
on previous block parameters that crept in as part of my captures
work a month or so ago.

John McCall 653dac4b0a dgregor accidentally killed this assert, but on investigation, it can fire
on invalid code and we don't really care, so kill it harder.

Chris Lattner dd1cb5b2ec Add 'previous declaration is here' note for param redefinition
errors, e.g.:

t.c:1:21: error: redefinition of parameter 'x'
int test(int x, int x);
                    ^
t.c:1:14: note: previous declaration is here
int test(int x, int x);
             ^

Fariborz Jahanian 5ec502e35b Complain if block-literal expression's parameter name is
missing (in c/objc mode). Fixes radar 7528255.

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).

John McCall 02dee0a46a Semantic checking for main().
Fix some invalid main() methods in the test suite that were nicely
exposed by the new checks.

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.

Tests and drivers updated, still need to shuffle dirs.

Chris Lattner 2ca529ce61 instead of forcing blocks on by default, make them default to off, but let
specific targets default them to on.  Default blocks to on on 10.6 and later.
Add a -fblocks option that allows the user to override the target's default.
Use -fblocks in the various testcases that use blocks.
