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 8b57697954 Eliminate &&s in tests.
- 'for i in $(find . -type f); do sed -e 's#\(RUN:.*[^ ]\) *&& *$#\1#g' $i | FileUpdate $i; done', for the curious.

Chris Lattner c45529b17b Fix rdar://6849429 - -Wunused-value with deeply nested macro expansion generates untraceable warnings
The "instantiated from" messages coming from the caret diagnostics system are 
basically walking the macro expansion tree, emitting each level as it goes.  However, it was
skipping certain leaves in the tree by skipping up the entire instantiation arm every time
it went up one spelling arm.  This caused it to miss some things.  For example, in this
testcase:

#define M1(x) x
#define M2 1;

void foo() {
 M1(M2)
}

we now print:

/Users/sabre/Desktop/clang-unused-value-macro.c:6:2: warning: expression result unused

 M1(M2)
 ^~~~~~
/Users/sabre/Desktop/clang-unused-value-macro.c:6:5: note: instantiated from:

 M1(M2)
    ^~
/Users/sabre/Desktop/clang-unused-value-macro.c:3:12: note: instantiated from:

#define M2 1;
           ^

Previously we didn't print the last line, so we never emitted the caret pointing to the 1!

Incidentally, the spaces between the lines is really noisy, I think we should reconsider
this heuristic (which adds them when the printed code starts too close to the start of the
line).

The regression test can't use -verify, because -verify doesn't catch notes for macro
instantiation history.
