Ted Kremenek 352a7081a8 -Wuninitialized: don't warn about uninitialized variables in unreachable code.

Ted Kremenek 03325c4be9 Add workaround for Sema issue found in <rdar://problem/9188004>, which leads to an assertion failure in the uninitialized variables analysis. The problem is that Sema isn't properly registering a variable in a DeclContext (which -Wuninitialized relies on), but
my expertise on the template instantiation logic isn't good enough to fix this problem for real.  This patch worksaround the
problem in -Wuninitialized, but we should fix it for real later.

Ted Kremenek ea6c20adaf Take 2: merge -Wuninitialized-experimental into -Wuninitialized. Only *must-be-uninitialized* warnings are reported, with *maybe-uninitialized* under a separate flag. I await any fallout/comments/feedback, although hopefully this will produce no noise for users.

Ted Kremenek e6a12a97d4 Move uninitialized variable checking back under -Wuninitialized-experimental. It is clear from user feedback that this warning is not quite ready.

Ted Kremenek 6c9cd14bf9 Don't suggest -Wuninitialized fixits for uninitialized enum types.

Ted Kremenek b3dbe28e31 Based on user feedback, swap -Wuninitialized diagnostics to have the warning refer to the bad use, and the note to the variable declaration.

Ted Kremenek 33d4b5eb66 Provide -Wuninitialized-experimental fixits
for floats, and also check if 'nil' is declared
when suggesting it for initializing ObjC pointers.

Ted Kremenek 39fa056342 Enhance -Wuninitialized-experimental diagnostics
to issue the warning at an uninitialized variable's
declaration, but to issue notes at possible
uninitialized uses (which could be multiple).

Ted Kremenek cdca8fa97d Relax CFG assertions in UninitializedValuesV2 when
handling pseudo-path sensitivity, and instead
use those assertion conditions as dynamic checks.
These assertions would be violated when analyzing
a CFG where some branches where optimized away
during CFG construction because their branch
conditions could be trivially determined.

Ted Kremenek b63931eef6 Teach UninitializedValuesV2 to implicitly reason about C++
references by monitoring whether an access to
a variable is solely to compute it's lvalue or
to do an lvalue-to-rvalue conversion (i.e., a load).
