(unsurprisingly) caret diagnostics. This is designed to bring some
organization to the monstrous EmitCaretDiagnostic function, and allow
factoring it more easily and with less mindless parameter passing.

Currently this just lifts the existing function into a method, and
splits off the obviously invariant arguments to be class members. No
functionality is changed, and there are still lots of warts to let
existing code continue functioning as-is. Definitely WIP, more cleanups
to follow.

It will become the default feature soon.

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.

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.

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.

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.
