This patch fixes the PPC eh_frame definitions for the personality and 
frame unwinding for PIC objects. It makes PIC build correctly creates
relative relocations in the '.rela.eh_frame' segments and thus avoiding
a text relocation that generates a DT_TEXTREL segments in link phase.

Add __has_feature support to detect if clang supports the explicit "atomic" keyword for ObjC properties.

Fixes <rdar://problem/12953378>.

Addresses LLVM PR 11661.

NSErrorChecker: remove quoting the parameter name in the diagnostic until we actually include it's name.

This is a possible regression of moving to using ImplicitNullDerefEvent.
Fixing this for real (including the parameter name) requires more
plumbing in ImplicitNullDerefEvent.  This is just a stop gap fix.

This prevents code like:

namespace {
class Foo {
  Foo(
  };
}  // comment

from causing segfaults (see llvm.org/PR14774).

The line information was changed when emitting debug information for all the
DeclRefExprs and we should change it back to get ready for PopClenupBlocks
called from FinishFunction.

Uses of clang_getSpellingLocation should eventually move to calling
clang_getFileLocation, and clang_getSpellingLocation should do what
its name represents and actually point at the 'spelling' location, e.g.
inside a macro definition if the spelling of a token came from that.

Took existing code from loop-convert tool and made it into a cpp11-migrate
transform. Pattern now set for having transform code in subdirectories. Related
changes:
- Makefile and CMakeLists.txt updated to support source files in
  subdirectories.
- At least one transform must be specified. syntax-only tests removed to
  reflect this.
- TODO: port over loop-convert tests.

A segfault used to clear the entire buffer. With this change, a message
to report a bug is displayed instead.

This should solve most cases similar to llvm.org/PR14774.

Added a page that describes how to to manual symbolication with LLDB from the command line, from python, and also how to use the build in modules to do symbolication.

Added SBTarget::EvaluateExpression() so expressions can be evaluated without needing a process.

Also fixed many functions that deal with clang AST types to be able to properly handle the clang::Type::Elaborated types ("struct foo", "class bar").

Move the loop vectorizer from O2 to O3. It looks like the increase in code size actually hurts the performance on many programs.

2. Add code to select the unroll factor based on register pressure.
3. Add bits to TargetTransformInfo to provide the number of registers.

Revert revision: 171467. This transformation is incorrect and makes some tests fail. Original message:

Simplified TRUNCATE operation that comes after SETCC. It is possible since SETCC result is 0 or -1.
Added a test.

Revert "Mark DIV/IDIV instructions hasSideEffects=1 because they can trap when dividing by 0. This is needed to keep early if conversion from moving them across basic blocks."

Changed two debug statements that state that a queue had finished being processed when said queue was really a list to state a list had finished being processed.
