e5d7c0d111 PreRA scheduler should avoid cloning compares. 
Added canClobberReachingPhysRegUse() to handle a particular pattern in
which a two-address instruction could be forced to interfere with
EFLAGS, causing a compare to be unnecessarilly cloned.
Fixes rdar://problem/5875261

1af1d2dfda Static relocation model Thumb jump table interworking. 
Make sure the low bit of the PC is set when loading an address directly
for jump tables in static relocation model.

dd71d9efb9 The asm parser currently selects the wrong encoding for non-conditional Thumb2 branches. However, this exposed a number of situations where the decoder was too permissive in allowing invalid instructions to decode successful. Specify additional fixed bits to close those gaps.

df24e0d185 Make sure we aren't deleting the landingpad instruction. 
The landingpad instruction is required in the landing pad block. Because we're
not deleting terminating instructions, the invoke may still jump to here (see
Transforms/SCCP/2004-11-16-DeadInvoke.ll). Remove all uses of the landingpad
instruction, but keep it around until code-gen can remove the basic block.

de17548520 When performing instruction selection for LDR_PRE_IMM/LDRB_PRE_IMM, we still need to preserve the sign of the index. This fixes miscompilations of Quicksort in the nightly testsuite, and hopefully others as well.

506f8078a8 Run the Thumb1 parser tests in Thumb2 mode, as well. 
Thumb2 is a superset of Thumb1, so all of the encodings should still work.

74f916342a Remove FIXME. Thumb2 MOV instruction will use separate custom tricks. 
When we want encoding T3 (the wide encoding), we can explicitly check for
that and twiddle the CanAcceptCarrySet accordingly. For now, just correctly
handle encodings T1 and T2 when in Thumb2 mode.

a4c1e9d88a Tweak Thumb1 ADD encoding selection a bit. 
When the destination register of an add immediate instruction is
explicitly specified, encoding T1 is preferred, else encoding T2 is
preferred.

ad3a292ff7 Put VMOVS widening under a command line option, off by default. 
It appears that our use of the imp-use and imp-def flags with
sub-registers is not yet robust enough to support this.

The failing test case is complicated, I am working on a reduction.
