Summary:
isClassMessage is an equivalent to isInstanceMessage for ObjCMessageExpr, but matches message expressions to classes.
isClassMethod and isInstanceMethod check whether a method declaration (or definition) is for a class method or instance method (respectively).

Default RegionStore bindings represent values that can be obtained by loading
from anywhere within the region, not just the specific offset within the region
that they are said to be bound to. For example, default-binding a character \0
to an int (eg., via memset()) means that the whole int is 0, not just
that its lower byte is 0.
Even though memset and bzero were modeled this way, it didn't work correctly
when applied to simple variables. Eg., in
int x;
memset(x, 0, sizeof(x));
we did produce a default binding, but were unable to read it later, and 'x'
was perceived as an uninitialized variable even after memset.
At the same time, if we replace 'x' with a variable of a structure or array
type, accessing fields or elements of such variable was working correctly,
which was enough for most cases. So this was only a problem for variables of
simple integer/enumeration/floating-point/pointer types.
Fix loading default bindings from RegionStore for regions of simple variables.
Add a unit test to document the API contract as well.

Summary:
This file defines the *Stencil* abstraction: a code-generating object, parameterized by named references to (bound) AST nodes. Given a match result, a stencil can be evaluated to a string of source code.
A stencil is similar in spirit to a format string: it is composed of a series of raw text strings, references to nodes (the parameters) and helper code-generation operations.
See thread on cfe-dev list with subject "[RFC] Easier source-to-source transformations with clang tooling" for background.

llvm-svn: 358691
Summary:
Currently clang-format uses ContinuationIndent to indent the contents of a raw
string literal that is the last parameter of the function call. This is to
achieve formatting similar to trailing:
```
f(1, 2, R"pb(
x: y)pb");
```
However this had the unfortunate consequence of producing format like this:
```
fffffff(1, 2,
R"pb(
a: b
)pb");
```
This patch makes clang-format consider indenting a trailing raw string param
after a newline based off the start of the format delimiter, producing:
```
fffffff(1, 2,
R"pb(
a: b
)pb");
```

llvm-svn: 358689
Summary:
Motivation/Context: in the code review system integrating with clang-tidy,
clang-tidy doesn't provide a human-readable description of the fix. Usually
developers have to preview a code diff (before vs after apply the fix) to
understand what the fix does before applying a fix.
This patch proposes that each clang-tidy check provides a short and
actional fix description that can be shown in the UI, so that users can know
what the fix does without previewing diff.
This patch extends clang-tidy framework to support fix descriptions (will add implementations for
existing checks in the future). Fix descriptions and fixes are emitted via diagnostic::Note (rather than
attaching the main warning diagnostic).
Before this patch:
```
void MyCheck::check(...) {
...
diag(loc, "my check warning") << FixtItHint::CreateReplacement(...);
}
```
After:
```
void MyCheck::check(...) {
...
diag(loc, "my check warning"); // Emit a check warning
diag(loc, "fix description", DiagnosticIDs::Note) << FixtItHint::CreateReplacement(...); // Emit a diagnostic note and a fix
}
```

Summary:
For example, a renamed type in a header file can conflict with declaration in
a random file that includes the header, but we should not consider the decl ambiguous if
it's not visible at the rename location. This improves consistency of generated replacements
when header file is included in different TUs.

As the unit test demonstrates, subtracting 1 from the offset was unnecessary.
The only user of this function was the plist file emitter (in Static Analyzer
and ARCMigrator). It means that a lot of Static Analyzer's plist arrows
are in fact off by one character. The patch carefully preserves this
completely incorrect behavior and causes no functional change,
i.e. no plist format breakage.

from the FixIt library (in clangTooling) to this new library.
We need to use this functionality in Refactoring/ and cannot access it if it
resides in Tooling/, because that would cause clangToolingRefactor to depend on
clangTooling, which would be a circular dependency.

Summary:
Currently clang-format would always emit a replacement for multi-block #include
sections if `IBS_Regroup`, even if the sections are correct:
```
% cat ~/test.h
#include <a.h>
#include "b.h"
% bin/clang-format --output-replacements-xml -style=google ~/test.h
<?xml version='1.0'?>
<replacements xml:space='preserve' incomplete_format='false'>
<replacement offset='0' length='30'>#include <a.h> #include "b.h"</replacement>
</replacements>
%
```
This change makes clang-format not emit replacements in this case.
The logic is similar to the one implemented for Java in r354452.
