 - Currently just an alias for --analyze, eventually we want to refit
   --analyze so that it is less automatic (i.e., does not force plist
   output and does not hard code the list of checks).

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.

Allow multiclass def names to contain "#NAME"" where TableGen replaces
#NAME# with the name of the defm instantiating the multiclass.  This is
useful for AVX instruction naming where a "V" prefix is standard
throughout the ISA.  For example:

multiclass SSE_AVX_Inst<...> {
   def SS : Instr<...>;
   def SD : Instr<...>;
   def PS : Instr<...>;
   def PD : Instr<...>;

   def V#NAME#SS : Instr<...>;
   def V#NAME#SD : Instr<...>;
   def V#NAME#PS : Instr<...>;
   def V#NAME#PD : Instr<...>;
}

defm ADD : SSE_AVX_Inst<...>;
