4f8aaa0928 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.

d84192fe4f 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.

e0e42bf0bb Run the Thumb1 parser tests in Thumb2 mode, as well. 
Thumb2 is a superset of Thumb1, so all of the encodings should still work.

b80ab8e369 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.

6154582983 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.
