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).

Daniel Dunbar a45cf5b6b0 Rename clang to clang-cc.
Tests and drivers updated, still need to shuffle dirs.

Douglas Gregor 75a45ba2a4 Adopt a more principled approach to invalid declarations:
- If a declaration is an invalid redeclaration of an existing name,
    complain about the invalid redeclaration then avoid adding it to
    the AST (we can still parse the definition or initializer, if any).
  - If the declaration is invalid but there is no prior declaration
    with that name, introduce the invalid declaration into the AST
    (for later error recovery).
  - If the declaration is an invalid redeclaration of a builtin that
    starts with __builtin_, we produce an error and drop the
    redeclaration. If it is an invalid redeclaration of a library
    builtin (e.g., malloc, printf), warn (don't error!) and drop the
    redeclaration.

If a user attempts to define a builtin, produce an error and (if it's
a library builtin like malloc) suggest -ffreestanding.

This addresses <rdar://problem/6097585> and PR2892. However, PR3588 is
still going to cause some problems when builtins are redeclared
without a prototype.

Steve Naroff 189d41f625 Fix <rdar://problem/6552648> error: redefinition of 'XCElementAnchorDelegate' as different kind of symbol.
At first glance, this looked like a recent regression (possibly created by http://llvm.org/viewvc/llvm-project?view=rev&revision=63354, which was the only recent change to this section of Sema::ActOnStartClassInterface()). After more investigation, it looks like an edge case bug that we didn't cover in our tests.

Chris Lattner 0369c57ac6 Make all the 'redefinition' diagnostics more consistent, and make the
"previously defined here" diagnostics all notes.

Chris Lattner e6447ef989 make some objc redefinition warnings more consistent: call definitions
"definitions", not declarations.  Point out the location of the 
original definition.

Chris Lattner 89026888ef move all objc sema tests into a new SemaObjC directory. Next step is to
remove the objc- prefix from the tests that use it.
