clang doesn't support yet.

IRgen no longer relies on isConstantInitializer, instead we just try
to emit the constant. If that fails then in C we emit an error
unsupported (this occurs when Sema accepted something that it doesn't
know how to fold, and IRgen doesn't know how to emit) and in C++ we
emit a guarded initializer.

This ends up handling a few more cases, because IRgen was actually
able to emit some of the constants Sema accepts but can't Evaluate().
For example, PR3398.

diagnostics.  I'm not sure I want to keep this, but hey, it's easy
and could be useful or something, even if guarded by a 
-fshow-me-tons-of-details option.  A silly example is:

#define A B
#define C A
#define D C

int y = D;

We now emit:

t.c:11:9: error: use of undeclared identifier 'B'
int y = D;
        ^
t.c:9:11: note: instantiated from:
#define D C
          ^
t.c:8:11: note: instantiated from:
#define C A
          ^
t.c:7:11: note: instantiated from:
#define A B
          ^

A more useful example is from tgmath:

t.c:4:9: error: no matching function for call to '__tg_acos'
 return acos(x);
        ^~~~~~~
/Users/sabre/llvm/Debug/Headers/tgmath-sofar.h:51:17: note: instantiated from:
#define acos(x) __tg_acos(x)
                ^
... candidate set follows ...

This does not yet print ranges in instantiation info, (e.g. highlighting the
range "__tg_acos(x)" in the last example), but that could be added if we 
decide this is a good idea :).

Thoughts and bug reports welcome!

fixing a fixme.  It would be even fancier to get the spelling of the token, but I
don't care *that* much :)

as the last non-note diagnostic that preceeded them.  This ensures
that diagnostics in main files which have notes with locations in 
system headers get all the bits and pieces emitted or not in a 
unit.  This fixes PR3215.

A couple of places where reused use operands should be marked kill. This is exposed by recent availability fallthrough changes.

- Move all analyzer options logic to AnalysisConsumer.cpp.
- Unified specification of stores/constraints/output to be:
   -analyzer-output=...
   -analyzer-store=...
   -analyzer-constraints=...
  instead of -analyzer-range-constraints, -analyzer-store-basic, etc.
- Updated drivers (ccc-analyzer, scan-builds, new ccc) to obey this new
  interface
- Updated test cases to conform to new driver options

functions, so if we're declaring a static we should implicitly declare
a library function by the same name (e.g., malloc, strdup). Fixes PR3592.
