In Thumb2 mode, lower frame indix references to:
...
add <rd>, sp, #<imm8>
ldr <rd>, [sp, #<imm8>]
When the offset from sp is multiple of 4 and in range of 0-1020.
This saves code size by utilizing 16-bit instructions.

Branch folding is folding a landing pad into a regular BB.
...
An exception is thrown via a call to _cxa_throw, which we don't expect to
return. Therefore, the "true" part of the invoke goes to a BB that has
'unreachable' as its only instruction. This is lowered into an empty MachineBB.
The landing pad for this invoke, however, is directly after the "true" MBB.
When the empty MBB is removed, the landing pad is directly below the BB with the
invoke call. The unconditional branch is removed and then the two blocks are
merged together.
The testcase is too big for a regression test.

Allow allocatable ranges from global live range splitting to be split again.
...
These intervals are allocatable immediately after splitting, but they may be
evicted because of later splitting. This is rare, but when it happens they
should be split again.
The remainder intervals that cannot be allocated after splitting still move
directly to spilling.
SplitEditor::finish can optionally provide a mapping from new live intervals
back to the original interval indexes returned by openIntv().
Each original interval index can map to multiple new intervals after connected
components have been separated. Dead code elimination may also add existing
intervals to the list.
The reverse mapping allows the SplitEditor client to treat the new intervals
differently depending on the split region they came from.
