Summary:
RegionStoreManager had an optimization which replaces references to empty
structs with UnknownVal. Unfortunately, this check didn't take into account
possible field members in base classes.
To address this, I changed this test to "is empty and has no base classes". I
don't consider it worth the trouble to go through base classes and check if all
of them are empty.

The environments can inject some declaration in every translation unit,
which can match very generic matchers, thus failing the tests.

Fix tests to be more specific.

We now count the original token's column directly when lexing the
tokens, where we already have all knowledge about where lines start.
Before this patch, formatting:
void f() {
\tg();
\th();
}
would incorrectly count the \t's as 1 character if only the line
containing h() was reformatted, and thus indent h() at offset 1.

Currently only constructor parameters stored in class-local storage are modified
to make use of the pass-by-value idiom but this is a base that can be be further
improved to handle more situations.
This commit is the same as r189363 with additionnal fixes for the build issues.

Summary:
Made UnicodeCharSet a class, perform validity checking inside its
constructor instead of each isCharInSet call, use std::binary_search instead of
own implementation.
This patch comes with a necessary change in clang (sent separately).

Some stubs only support g/G packets for registers.
This change makes sure that we check if remote stub supports 'p' packet before using it.

We added layout edges to the head atoms in grouped sections. That was wrong,
because the head atom needs to be followed by the other atoms in the *same*
section, not by the other section contents. With this patch, layout edges are
added from tail atom, which is the last atom in a section, to head atom.
llvm-svn: 189573
Because of a bug, the last atom of each section contained a garbage at the
end of its data. In most cases the garbage is harmless but it could have cause
SEGV.

Original commit message:
Add getUnrollingPreferences to TTI
Allow targets to customize the default behavior of the generic loop unrolling
transformation. This will be used by the PowerPC backend when targeting the A2
core (which is in-order with a deep pipeline), and using more aggressive
defaults is important.

This uses the TargetSubtargetInfo::useAA() function to control the defaults of
the -combiner-alias-analysis and -combiner-global-alias-analysis options.
llvm-svn: 189564
There are several optional (off-by-default) features in CodeGen that can make
use of alias analysis. These features are important for generating code for
some kinds of cores (for example the (in-order) PPC A2 core). This adds a
useAA() function to TargetSubtargetInfo to allow these features to be enabled
by default on a per-subtarget basis.
Here is the first use of this function: To control the default of the
-enable-aa-sched-mi feature.

Fixes PR17018. Only partial test coverage because I don't want
to try to write a test which generates a file whose name contains a newline.
