Anna Zaks 8e492c2380 [analyzer] Address Jordan’s review of r178309 - do not register an extra visitor for nil receiver
We can check if the receiver is nil in the node that corresponds to the StmtPoint of the message send.
At that point, the receiver is guaranteed to be live. We will find at least one unreclaimed node due to
my previous commit (look for StmtPoint instead of PostStmt) and the fact that the nil receiver nodes are tagged.

current path, so relax the search to look for any StmtPoint.

Argyrios Kyrtzidis bd8cd3ed85 When looking for overridden ObjC methods, don't ignore 'hidden' ones.
When using modules we should not ignore overridden methods from
categories that are hidden because the module is not visible.
This will give more consistent results (when imports change) and it's more
correct since the methods are indeed overridden even if they are not "visible"
for lookup purposes.

Benjamin Kramer 054faa5a48 Sema: Warn on sizeof on binary ops on decayed arrays.
The array will decay into a pointer, creating an unexpected result.
sizeof(array + int) is an easy to make typo for sizeof(array) + int.

This was motivated by a NetBSD security bug, used sizeof(key - r) instead of
sizeof(key) - r, reducing entropy in a random number generator.

Anna Zaks 333481b90b [analyzer] Add support for escape of const pointers and use it to allow “newed” pointers to escape
Add a new callback that notifies checkers when a const pointer escapes. Currently, this only works
for const pointers passed as a top level parameter into a function. We need to differentiate the const
pointers escape from regular escape since the content pointed by const pointer will not change;
if it’s a file handle, a file cannot be closed; but delete is allowed on const pointers.

This should suppress several false positives reported by the NewDelete checker on llvm codebase.

Anna Zaks 05fb371efc [analyzer] Apply the suppression rules to the nil receiver only if the value participates in the computation of the nil we warn about.
We should only suppress a bug report if the IDCed or null returned nil value is directly related to the value we are warning about. This was
not the case for nil receivers - we would suppress a bug report that had an IDCed nil receiver on the path regardless of how it’s
related to the warning.

1) Thread EnableNullFPSuppression parameter through the visitors to differentiate between tracking the value which
is directly responsible for the bug and other values that visitors are tracking (ex: general tracking of nil receivers).
2) in trackNullOrUndef specifically address the case when a value of the message send is nil due to the receiver being nil.

Summary:
This also relaxes the requirement on Windows that the member pointer
class type be a complete type (http://llvm.org/PR12070).  We still ask
for a complete type to instantiate any templates (MSVC does this), but
if that fails we continue as normal, relying on any inheritance
attributes on the declaration.

Ted Kremenek 0dd8feee93 Add CFG logic to create a conditional branch for modeling static initializers.
This is an optional variant of the CFG.  This allows analyses to model whether
or not a static initializer has run, e.g.:

  static Foo x = bar();

For basic dataflow analysis in Sema we will just assume that the initializer
always runs.  For the static analyzer we can use this branch to accurately
track whether or not initializers are on.

This patch just adds the (opt-in) functionality to the CFG.  The
static analyzer still needs to be modified to adopt this feature.

Argyrios Kyrtzidis c36633c47a [Parser] Don't code-complete twice.
When we are consuming the current token just to enter a new token stream, we push
the current token in the back of the stream so that we get it again.

Unfortunately this had the effect where if the current token is a code-completion one,
we would code-complete once during consuming it and another time after the stream ended.

Fix this by making sure that, in this case, ConsumeAnyToken() will consume a code-completion
token without invoking code-completion.

Jordan Rose 3503cb3572 [analyzer] Use evalBind for C++ new of scalar types.
These types will not have a CXXConstructExpr to do the initialization for
them. Previously we just used a simple call to ProgramState::bindLoc, but
that doesn't trigger proper checker callbacks (like pointer escape).

Found by Anton Yartsev.

Anna Zaks 22fa6ecc14 [analyzer] Ensure that the node NilReceiverBRVisitor is looking for is not reclaimed
The visitor should look for the PreStmt node as the receiver is nil in the PreStmt and this is the node. Also, tag the nil
receiver nodes with a special tag for consistency.

Argyrios Kyrtzidis 0f06b98387 [modules] Make sure enabled diagnostic pragmas inside the module don't affect the translation unit that
imports the module.

Getting diagnostic sections from modules properly working is a fixme.

Douglas Gregor bf7fc9c542 <rdar://problem/13509689> Introduce -module-file-info option that provides information about a particular module file.
This option can be useful for end users who want to know why they
ended up with a ton of different variants of the "std" module in their
module cache. This problem should go away over time, as we reduce the
need for module variants, but it will never go away entirely.

Argyrios Kyrtzidis fff55a028b [lib/Headers] Break the module import cycle between _Builtin_intrinsics.sse and _Builtin_intrinsics.sse2
Module "sse" implicitly exports module "sse2".
This is bad because we also have module "sse2" export module "sse" (as intended) so we end up with a cycle
in the module import graph:
1. sse2 -> (also imports) sse
2. sse -> (also imports) sse2

To eliminate the cycle remove 2.; importing module "sse2" will also import module "sse", but just importing
module "sse" will not also import module "sse2".
