Resubmit with fix. Properly remove the instructions except for landingpad, which should be removed only when its invokes are.

The landingpad instruction can be removed only when its invokes are removed.

disassemble with no arguments disassembles at the pc.  Also got "disassemble -f" to work, that had gotten broken at some point in the past.

The initial incentive was to fix a crash when PCH chaining categories
to an interface, but the fix was done in the "modules way" that I hear
is popular with the kids these days.

Each module stores the local chain of categories and we combine them
when the interface is loaded. We also warn if non-dependent modules
introduce duplicate named categories.

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.

(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.

-fobjc-default-synthesize-properties option
and is off by default pending further testing.
It will become the default feature soon.

Make sure the low bit of the PC is set when loading an address directly
for jump tables in static relocation model.

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.
