90b5a08e1f ARM Thumb blx instruction fixup has same data range as bl. 
These fixups are handled poorly in general, and should have a single
contiguous range of bits per fixup type, but that's not how they're
currently organized, so for now in complex ones like for blx, we just tell the
emitter it's OK for the fixup to munge any bit it wants.

2ac0e6be05 Add the support in code-gen for the landingpad instruction lowering. 
The landingpad instruction is lowered into the EXCEPTIONADDR and EHSELECTION
SDNodes. The information from the landingpad instruction is harvested by the
'AddLandingPadInfo' function. The new EH uses the current EH scheme in the
back-end. This will change once we switch over to the new scheme. (Reviewed by
Jakob!)

70939ee141 ARM clean up the imm_sr operand class representation. 
Represent the operand value as it will be encoded in the instruction. This
allows removing the specialized encoder and decoder methods entirely. Add
an assembler match class while we're at it to lay groundwork for parsing the
thumb shift instructions.

0906a7c46c Don't optimize the landing pad exit block. 
One way to exit the loop is through an unwind edge. However, that may involve
splitting the critical edge of the landing pad, which is non-trivial. Prevent
the transformation from rewriting the landing pad exit loop block.

Things are much saner now. We no longer need to modify the laning pads, because
of the invariants we impose upon them. The only thing DwarfEHPrepare needs to do
is convert the 'resume' instruction into a call to '_Unwind_Resume'.
