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.

Anna Zaks 4e16b29c13 [analyzer] Refactor BugReport::getLocation and PathDiagnosticLocation::createEndOfPath for greater code reuse
The 2 functions were computing the same location using different logic (each one had edge case bugs that the other
one did not). Refactor them to rely on the same logic.

The location of the warning reported in text/command line output format will now match that of the plist file.

There is one change in the plist output as well. When reporting an error on a BinaryOperator, we use the location of the
operator instead of the beginning of the BinaryOperator expression. This matches our output on command line and
looks better in most cases.

Anna Zaks 58b961d176 [analyzer] Plist: change the type of issue_hash from int to string.
This gives more flexibility to what could be stored as issue_hash.

Jordan Rose 4d9fbd7ec4 [analyzer] -analyzer-ipa=inlining is now the default. Remove it from tests.
The actual change here is a little more complicated than the summary above.
What we want to do is have our generic inlining tests run under whatever
mode is the default. However, there are some tests that depend on the
presence of C++ inlining, which still has some rough edges. These tests have
been explicitly marked as -analyzer-ipa=inlining in preparation for a new
mode that limits inlining to C functions and blocks. This will be the
default until the false positives for C++ have been brought down to
manageable levels.

Anna Zaks 4c03dfd4b1 [analyzer] Solve another source of non-determinism in the diagnostic
engine.

The code that was supposed to split the tie in a deterministic way is
not deterministic. Most likely one of the profile methods uses a
pointer. After this change we do finally get the consistent diagnostic
output. Testing this requires running the analyzer on large code bases
and diffing the results.

Ted Kremenek 54baf2e57d PlistDiagnostics: force the ranges for control-flow edges to be single locations, forcing
adjacent edges to have compatible ranges.  This simplifies the layout logic for some clients.

Ted Kremenek a85f38ba3a Rework ExprEngine::evalLoad and clients (e.g. VisitBinaryOperator) so that when we generate a new ExplodedNode
we use the same Expr* as the one being currently visited.  This is preparation for transitioning to having
ProgramPoints refer to CFGStmts.

This required a bit of trickery.  We wish to keep the old Expr* bindings in the Environment intact,
as plenty of logic relies on it and there is no reason to change it, but we sometimes want the Stmt* for
the ProgramPoint to be different than the Expr* being used for bindings.  This requires adding an extra
argument for some functions (e.g., evalLocation).  This looks a bit strange for some clients, but
it will look a lot cleaner when were start using CFGStmt* in the appropriate places.

As some fallout, the diagnostics arrows are a bit difference, since some of the node locations have changed.
I have audited these, and they look reasonable.

Anna Zaks 943c680605 [analyzer] Change the order in which we analyze the functions under
inlining to be the reverse of their declaration.

This optimizes running time under inlining up to 20% since we do not
re-analyze the utility functions which are usually defined first in the
translation unit if they have already been analyzed while inlined into
the root functions.

Anna Zaks 0af3e06ff6 [analyzer] Rework inlining related command line options.
- Remove -analyzer-inline-call.
 - Add -analyzer-ipa=[none|inlining]
 - Add -analyzer-inlining-mode to allow experimentation for
different performance tuning methods.

Ted Kremenek 60a7820ffe Reapply r151317, but when computing the PathDiagnostic profile and size keep into account the nested structure. Also fix a problem with how
inlining impacted Plist diagnostics, and adjust some ranges in the Plist output due to richer information.

Ted Kremenek 8e4c4266de Rework flushing of diagnostics to PathDiagnosticConsumer. Now all the reports are batched up before being flushed
to the underlying consumer implementation.  This allows us to unique reports across analyses to multiple functions (which
shows up with inlining).
