offset from a 32 bit aligned base as follows:

  ldw low, base[offset >> 2]
  ldw high, base[(offset >> 2) + 1]
  shr low_shifted, low, (offset & 0x3) * 8
  shl high_shifted, high, 32 - (offset & 0x3) * 8
  or result, low_shifted, high_shifted

Expand 32 bit loads / stores with 16 bit alignment into two 16 bit
loads / stores.

a big code size win since before they were expanding to upto 16
instructions.

Avoid remat'ing instructions whose def have sub-register indices for now. It's just really really hard to get all the cases right.

generator can know the top bits are zero, not undefined.

ValueManager::makeArrayIndex()/convertArrayIndex() methods.  This
handles yet another crash case when reasoning about array indices of
different bitwidth and signedness.

means that two separate raw_ostreams are doing buffering before data is
sent to the underlying stream. Besides the inefficiency of redundant
buffering, the second level of buffering doesn't recieve flush()
requests.

Fix this by having formatted_raw_ostream set the underlying raw_ostream
to be unbuffered. This eliminates inefficiency due to redundant buffering,
and it makes the flush() disconnect harmless.

This fixes PR4559.
