involving 'restrict', place restrict on the pointer type rather than
on the pointee type. Also make sure that we gather restrict from the
pointer type. Fixes PR12854 and the major part of PR11093.

so we can destroy it even if it was constructed with "DelayInitialization = true",

When we timeout or exceed a max number of blocks within an inlined
function, we retry with no inlining starting from a node right before
the CallEnter node. We assume the state of that node is the state of the
program before we start evaluating the call. However, the node pruning
removes this node as unimportant.
Teach the node pruning to keep the predecessors of the call enter nodes.

show-enabled uses the command line you give it to build a CompilerInstance,
so any flags you pass will be processed as if running clang proper.

but different nested name specifiers to quietly clobber each other so
only one remains if they do not refer to the same NamedDecl. Fixes

This is a large class of false positives where anonymous enums are used to
declare constants (see Clang's Diagnostics.h for example). A small number of
true positives could probably be found in this bucket by still warning if the
anonymous enum is used in a declarator (enum { ... } x;) but so far we don't
believe this to be a source of significant benefit so I haven't bothered to
preserve those cases.

This comes up in the begin/end calls of a range-for (see the included test
case). Other suggestions are welcome, though this seems to do the trick without
regressing anything.

-Wsometimes-uninitialized diagnostics to make it clearer that the cause
of the issue may be a condition which must always evaluate to true or
false, rather than an uninitialized variable.
To emphasize this, add a new note with a fixit which removes the
impossible condition or replaces it with a constant.
Also, downgrade the diagnostic from -Wsometimes-uninitialized to
-Wconditional-uninitialized when it applies to a range-based for loop,
since the condition is not written explicitly in the code in that case.
