19810417cb [PowerPC] Miscellaneous fast-isel test cases.
Here are a few more tests that now pass after the recent fast-isel
commits.

b3f46e50b4 [PowerPC] Add loads, stores, and related things to fast-isel.
This is the next big chunk of fast-isel code.  The primary purpose is
to implement selection of loads and stores, but there is a lot of
drag-along to support this.  The common code to analyze addresses for
both loads and stores is substantial.  It's also necessary to add the
materialization code for global values.

Related to load-store processing is the code to fold loads into
integer extends, since otherwise we generate lots of redundant
instructions.  We also need to add some overrides to some FastEmit
routines to ensure we don't assign GPR 0 to a virtual register when
this would change the meaning of an instruction.

I added handling selection of a few binary arithmetic instructions, to
enable committing some test cases I wrote a while back.

Finally, ap couple of miscellaneous changes:
 * I cleaned up some poor style from a previous patch in
   PPCISelLowering.cpp, pointed out by David Blaikie.
 * I enlarged the Addr.Offset field to avoid sign problems with 32-bit
   offsets.

bb860a63ef Change default # of digits for APFloat::toString
This is a re-commit of r189442; I'll follow up with clang changes.

The previous default was almost, but not quite enough digits to
represent a floating-point value in a manner which preserves the
representation when it's read back in.  The larger default is much
less confusing.

I spent some time looking into printing exactly the right number of
digits if a precision isn't specified, but it's kind of complicated,
and I'm not really sure I understand what APFloat::toString is supposed
to output for FormatPrecision != 0 (or maybe the current API specification
is just silly, not sure which).  I have a WIP patch if anyone is interested.

ea5d96e1cf DIBuilder: retain a type when created with a unique identifier.
createClassType, createStructType, createUnionType, createEnumerationType,
and createForwardDecl will retain a type when created with a unique identifier,
to make sure they are treated as used even when all uses are replaced with
the identifiers.

Use TrackingVH<MDNode> instead of MDNode in AllRetainTypes, since the created
node can later be updated.

The change will be tested when clients of DIBuilder start to pass in non-empty
unique identifier.

lane.

abbc8335ad isCharInSet refactoring.
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).

198ffea54f Revert: r189565 - Add getUnrollingPreferences to TTI
Revert unintentional commit (of an unreviewed change).

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.

1613794ae8 Add useAA() to TargetSubtargetInfo
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.

2fd78a4651 Vectorizer/PassManager: I am working on moving the vectorizer out of the SCC passes. This patch moves the SLP-vectorizer and BB-vectorizer back into SCC passes for two reasons:
1. They are a kind of cannonicalization.
2. The performance measurements show that it is better to keep them in.

There should be no functional change if you are not enabling the LateVectorization mode.
