We don't need separate thumb1 instructions tADDSi3 etc. for addc and subc. The "normal" version always modify condition register CPSR so we should just use def : pat to match to the same instructions.

and replace the 'clang-cc' option '-analyzer-store=basic-new-cast' with
'-analyzer-store=basic-old-cast'. We'll keep the old CastRegion implementation
around for a little while for regression testing.

compute a full tree digest by over 50% on very small cases, and potentially much
larger on others.

Use getAsmName() method instead of accessing AsmName field directly.

Redesign this to avoid standard stream classes.  This stream class
provides pretty -printing of comments and other such things in asm
files.

This is part of the fix for pr4521.

This started as a small change, I swear.  Unfortunately, lots of things call the [I|F]CmpInst constructors.  Who knew!?

Add some hooks that a redesigned AsmStream needs to do its job.  These
allow derived classes to examine the stream buffer before it's flushed.

merge the new functionality and unittests into ConstantRange. Thanks to
Nick Lewycky for pointing out that it isn't necessary to have two separate
classes here.

Initial support for load / store multiple opt pass Thumb2 support (post-allocation only). It's kind of there, but not quite. I'll return to this later.

is modified. Otherwise, the unwinder will get confused. The old code (before I
started my hacking) did this. It dropped on the floor, because I wasn't aware of
this requirement.

On the plus side, if we use "alloca" in a function, we create frame pointers
even with -fomit-frame-pointer is enabled!

This is a Good Thing(tm)!!!

Fix ldrd / strd address mode matching code. It allows for +/- 8 bit offset. Also change the printer to make the scale 4 explicit.

Note, we are not yet generating these instructions.

what ConstantRange does for unsigned integers. Factor out a
common base class for common functionality.

Add some new functions for performing arithmetic on constant
ranges. Some of these are currently just stubbed out with
conservative implementations.

Add unittests for ConstantRange and ConstantSignedRange.

DAGTypeLegalizer::PromoteIntRes_EXTRACT_VECTOR_ELT take advantage of 
this new flexibility to simplify the code and make it deal with unusual 
vectors (like <4 x i1>) correctly.  Fixes PR3037.
