Chris Lattner 54fe883203 move gep decomposition out of ValueTracking into BasicAA. The form of
decomposition that it is doing is very basicaa specific and is only used
by basicaa.

Jim Grosbach e0e9b3013f Add hook for re-using virtual base registers for local stack slot access.
Nothing fancy, just ask the target if any currently available base reg
is in range for the instruction under consideration and use the first one
that is. Placeholder ARM implementation simply returns false for now.

Kalle Raiskila e60b5161d1 Fix a bug with insertelement on SPU.

Kalle Raiskila ab49360f59 Remove all traces of v2[i,f]32 on SPU.
The "half vectors" are now widened to full size by the legalizer.
The only exception is in parameter passing, where half vectors are 
expanded. This causes changes to some dejagnu tests.

Chris Lattner 3c603024bb Fix PR7755: knowing something about an inval for a pred
from the LHS should disable reconsidering that pred on the
RHS.  However, knowing something about the pred on the RHS

happening.

Chris Lattner ce3b2c3f77 Fix the rest of rdar://8318441 which happens when a raw_fd_ostream
(e.g. errs()) fails in close() due to (e.g.) a broken pipe.  As
previously written, the had_error() flag would get set and then
the raw_ostream dtor would report a fatal error.  There is nothing
the client can do about this and we have no way to report the error,
so just eat it.

Chris Lattner 6217082dc3 report_fatal_error can't use errs(), because errs() can call

Dan Gohman ed2b005842 Tweak IVUsers' concept of "interesting" to exclude add recurrences
where the step value is an induction variable from an outer loop, to
avoid trouble trying to re-expand such expressions. This effectively
hides such expressions from indvars and lsr, which prevents them
from getting into trouble.

Jim Grosbach 3cf08661f4 Add materialization of virtual base registers for frame indices allocated into
the local block. Resolve references to those indices to a new base register.
For simplification and testing purposes, a new virtual base register is
allocated for each frame index being resolved. The result is truly horrible,
but correct, code that's good for exercising the new code paths.

Next up is adding thumb1 support, which should be very simple. Following that
will be adding base register re-use and implementing a reasonable ARM
heuristic for when a virtual base register should be generated at all.
