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.

Thumb2 is a superset of Thumb1, so all of the encodings should still work.

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.

Fill in type legalization for MERGE_VALUES in all the various cases.  Patch by Micah Villmow.  (No testcase because the issue only showed up in an out-of-tree backend.)

and does the Sema on their body after the entire 
class/category @implementation is seen. This change allows messaging 
of forward private methods, as well as, access to 
synthesized ivars of properties with foward synthesize
declarations; among others. In effect, this patch removes
several restrictions placed on objective-c due to in-place
semantics processing of methods.

Emit a repeated sequence of bytes using .zero.  This saves an enormous

When the destination register of an add immediate instruction is
explicitly specified, encoding T1 is preferred, else encoding T2 is
preferred.

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.

This was intended to land with the main work of instantiation ->

commit it. Very sorry for that...

Make sure we don't crash when -miphoneos-version-min is specified on x86.  Hopefully this will fix gcc testsuite failures.
