In C++, constants captured by lambdas (and blocks) are not actually stored

case, they will have no binding when we go to look them up. Previously,
RegionStore thought they were uninitialized stack variables; now, it checks
to see if they are a constant we know how to evaluate, using the same logic
as r175026.

This particular code path is only for scalar variables. Constant arrays and
structs are still unfortunately unhandled; we'll need a stronger solution
for those.

This may have a small performance impact, but only for truly-undefined
local variables, captures in a non-inlined block, and non-constant globals.

Daniel Jasper [Thu, 14 Feb 2013 09:58:41 +0000 (09:58 +0000)]
Remove the trailing whitespace of formatted lines.

So far, clang-format has always assumed the whitespace belonging to the
subsequent token. This has the negative side-effect that when
clang-format formats a line, it does not remove its trailing whitespace,
as it belongs to the next token.

Thus, this patch fixes most of llvm.org/PR15062.

We are not zapping a file's trailing whitespace so far, as this does not
belong to any token we see during formatting. We need to fix this in a
subsequent patch.
