Nico Weber cdfb1ae7f7 Improve fixit for comparison operator on lhs of bitwise operator. 
Before:
test.cc:2:18: note: place parentheses around the == expression to silence this warning
  if (0 == flags & 0xdd)
                 ^
                   (   )

Now:
test.cc:2:18: note: place parentheses around the == expression to silence this warning
  if (0 == flags & 0xdd)
                 ^
      (         )

Argyrios Kyrtzidis 3c9aaf1ab8 Initialize the non-target-dependent fields of the Preprocessor in its constructor 
so we can destroy it even if it was constructed with "DelayInitialization = true",
and we didn't end up calling Preprocessor::Initialize.

Simon Atanasyan 590ad8f515 MIPS: Factor out code selects the float ABI as determined by -msoft-float, 
-mhard-float, and -mfloat-abi= to the new function getMipsFloatABI. That

Anna Zaks 7ba2615047 [analyzer] Rely on canBeInlined utility instead of checking CallExpr 
explicitly.

This will make it easier to add inlining support to more expressions.

Anna Zaks bec49efdf2 [analyzer] Fix a spurious undef value warning. 
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.

Kaelyn Uhrain 34fab5598d In TypoCorrectionConsumer, BestResults to CorrectionResults to lessen 
the confusion among all of the uses of Best* in relation to the set of
possible typo correction results. Also add a method to return the set of
typo corrections that have the single best edit distance--it returns the
second half of the first pair in TypoEditDistanceMap (with
getBestEditDistance already returning the first half).

Anna Zaks 2774f99913 [analyzer] Cleanup for r157721. 
We should lock the number of elements after the initial parsing is
complete. Recursive AST visitors in AnalyzesConsumer and CallGarph can
trigger lazy pch deserialization resulting in more calls to
HandleTopLevelDecl and appending to the LocalTUDecls list. We should
ignore those.

Ted Kremenek 16704bb15b Allow some BugReports to opt-out of PathDiagnostic callstack pruning until we have significantly 
improved the pruning heuristics.  The current heuristics are pretty good, but they make diagnostics
for uninitialized variables warnings particularly useless in some cases.

David Blaikie 7e6ad46275 Disable -Wunique-enum for anonymous enums. 
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.
