-Wsometimes-uninitialized. This detects cases where an explicitly-written branch
inevitably leads to an uninitialized variable use (so either the branch is dead
code or there is an uninitialized use bug).

This chunk of warnings tentatively lives within -Wuninitialized, in order to
give it more visibility to existing Clang users.

Implement the C++11 discarded value expression rules for volatile lvalues.  <rdar://problem/10790820>.

llvm-svn: 157420

A minor tweak to the new volatile lvalue warning: don't warn on "(void)x", where "x" refers to a local variable.  This should silence a useless warning in compiler-rt and other places.

This issue was that the source location was pointing to a
non-printable character and so CaretEnd was pointing one
_column_ past the caret but not one _character_ past the
caret. So the conversion between column and byte locations
wasn't working (because the conversion is only valid from
the first column or byte of a character).

volatile reference to a temporary is not viable. My interpretation is that
DR1152 was a bugfix, not a rule change for C++11, so this is not conditional on
the language mode. This matches g++'s behavior.

llvm-svn: 157370

Add a warning to diagnose statements in C++ like "*(volatile int*)x;".  Conceptually, this is part of -Wunused-value, but I added a separate flag -Wunused-volatile-lvalue so it doesn't get turned off by accident with -Wno-unused-value.  I also made a few minor improvements to existing unused value warnings in the process.  <rdar://problem/11516811>.

start with a cv-qualifier. DeclaratorDecl::getTypeSpecStartLoc() does not
produce the location of the first type-specifier (the cv-qualifier) in this
case, because we don't track source locations for cv-qualifiers.

No test here: I've not found a way to test this with a lit-style test, and
introducing a gtest test for this seems unwarranted. Suggestions welcome!

pointer, but such folding encounters side-effects, ignore the side-effects
rather than performing them at runtime: CodeGen generates wrong code for
__builtin_object_size in that case.
