Dan Gohman 9396b42ca4 When computing a new ConservativeResult, intersect it with 
the old one instead of replacing it, to be more precise.

Dan Gohman 0865966440 Rework scev-aa's basic computation so that it doesn't depend 
on ScalarEvolution successfully folding and preserving
range information for both A-B and B-A. Now, if it gets
either one, it's sufficient.

Jakob Stoklund Olesen f888911932 Begin implementation of an inline spiller. 
InlineSpiller inserts loads and spills immediately instead of deferring to
VirtRegMap. This is possible now because SlotIndexes allows instructions to be
inserted and renumbered.

This is work in progress, and is mostly a copy of TrivialSpiller so far. It
works very well for functions that don't require spilling.

Bill Wendling 1767723dbe Introducing the "linker_weak" linkage type. This will be used for Objective-C 
metadata types which should be marked as "weak", but which the linker will
remove upon final linkage. For example, the "objc_msgSend_fixup_alloc" symbol is
defined like this:

       .globl l_objc_msgSend_fixup_alloc
       .weak_definition l_objc_msgSend_fixup_alloc
       .section __DATA, __objc_msgrefs, coalesced
       .align 3
l_objc_msgSend_fixup_alloc:
        .quad   _objc_msgSend_fixup
        .quad   L_OBJC_METH_VAR_NAME_1

This is different from the "linker_private" linkage type, because it can't have
the metadata defined with ".weak_definition".

Jakob Stoklund Olesen dadea5b178 Fix the handling of partial redefines in the fast register allocator. 
A partial redefine needs to be treated like a tied operand, and the register
must be reloaded while processing use operands.

This fixes a bug where partially redefined registers were processed as normal
defs with a reload added. The reload could clobber another use operand if it was
a kill that allowed register reuse.

Bob Wilson d91d5bfc95 Fix a register scavenger crash when dealing with undefined subregs. 
The LowerSubregs pass needs to preserve implicit def operands attached to
EXTRACT_SUBREG instructions when it replaces those instructions with copies.

Bob Wilson ab0819e10d Add support for encoding NEON VMOV (from core register to scalar) instructions. 
The encoding is the same as VMOV (from scalar to core register) except that
the operands are in different places.

Bob Wilson 83b993a977 The t2MOVi16 and t2MOVTi16 instructions do not set CPSR. Trying to add 
a CPSR operand to them causes an assertion failure, so apparently these
instructions haven't been getting a lot of use.

Duncan Sands 17f1ca8793 Return Changed. This required setting Changed if dbg metadata 
is stripped off.  Currently set unconditionally, since the API
does not provide a way of working out if anything was actually
stripped off.

Rafael Espindola 38a7d7cbc3 Add a VT argument to getMinimalPhysRegClass and replace the copy related uses 
of getPhysicalRegisterRegClass with it.

If we want to make a copy (or estimate its cost), it is better to use the
smallest class as more efficient operations might be possible.
