George Karpenkov 363dd8e4b8 [analyzer] [NFC] Reverse the argument order for "diff" in tests
The current argument order has "expected" and "actual" the wrong way around,
so that the diff shows the change from expected to actual, not from actual to expected.

Namely, if the expected diagnostics contains the string "foo", but the analyzer emits "bar",
we really want to see:

```
- foo
+ bar
```

not

```
- bar
+ foo
```

since adapting to most changes would require applying that diff to the expected output.

George Karpenkov 391650912a [analyzer] [NFC] Remove unused Extensive diagnostic setting,
Rename AlternateExtensive to Extensive.
In 2013, five years ago, we have switched to AlternateExtensive
diagnostics by default, and Extensive was available under unused,
undocumented flag.
This change remove the flag, renames the Alternate
diagnostic to Extensive (as it's no longer Alternate), and ports the
test.

Gabor Horvath efec16307c [analyzer] Bug identification
This patch adds hashes to the plist and html output to be able to identfy bugs
for suppressing false positives or diff results against a baseline. This hash
aims to be resilient for code evolution and is usable to identify bugs in two
different snapshots of the same software. One missing piece however is a 
permanent unique identifier of the checker that produces the warning. Once that
issue is resolved, the hashes generated are going to change. Until that point
this feature is marked experimental, but it is suitable for early adoption.

Jordan Rose 5e2b3a30a0 [analyzer] Enable the new edge algorithm by default.
...but don't yet migrate over the existing plist tests. Some of these
would be trivial to migrate; others could use a bit of inspection first.
In any case, though, the new edge algorithm seems to have proven itself,
and we'd like more coverage (and more usage) of it going forwards.

Ted Kremenek 37c777ecc0 [analyzer] Use 'MemRegion::printPretty()' instead of assuming the region is a VarRegion.
Fixes PR15358 and <rdar://problem/13295437>.

Along the way, shorten path diagnostics that say "Variable 'x'" to just
be "'x'".  By the context, it is obvious that we have a variable,
and so this just consumes text space.

Anna Zaks 6bab4ef4e8 [analyzer] Replace "-analyzer-ipa" with "-analyzer-config ipa".
The idea is to eventually place all analyzer options under
"analyzer-config". In addition, this lays the ground for introduction of
a high-level analyzer mode option, which will influence the
default setting for IPAMode.

Ted Kremenek a5958869f6 TrackConstraintBRVisitor and ConditionBRVisitor can emit similar
path notes for cases where a value may be assumed to be null, etc.
Instead of having redundant diagnostics, do a pass over the generated
PathDiagnostic pieces and remove notes from TrackConstraintBRVisitor
that are already covered by ConditionBRVisitor, whose notes tend
to be better.

Ted Kremenek 7c15040e98 Fix bug in ConditionBRVisitor where for C++ (and not C) we were not ignoring
implicit pointer-to-boolean conversions in condition expressions.  This would
result in inconsistent diagnostic emission between C and C++.

A consequence of this is now ConditionBRVisitor and TrackConstraintBRVisitor may
emit redundant diagnostics, for example:

  "Assuming pointer value is null" (TrackConstraintBRVisitor)
  "Assuming 'p' is null" (ConditionBRVisitor)

We need to reconcile the two, and perhaps prefer one over the other in some
cases.

Jordan Rose 6ee44e1f03 [analyzer] Look through all casts when trying to track constraints.

Jordan Rose a3e3343e51 [analyzer] Add plist output checks for all four "path notes" tests.
No functionality change, but from now on, any new path notes should be
tested both with plain-text output (for ease of human auditing) and with
plist output (to ensure control flow and events are being correctly
represented in Xcode).

Jordan Rose cfb4eb293f [analyzer] When a symbol is null, we should track its constraints.
Because of this, we would previously emit NO path notes when a parameter
is constrained to null (because there are no stores). Now we show where we
made the assumption, which is much more useful.
