0d65748f8f Expand unaligned 32 bit loads from an address which is a constant 
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.

eb8036be44 Custom lower unaligned 32 bit stores and loads into libcalls. This is 
a big code size win since before they were expanding to upto 16
instructions.

7a6b20df7f Let callers decide the sub-register index on the def operand of rematerialized 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.

e12dcd84ca use SUBREG_TO_REG instead of INSERT_SUBREG, this way the code 
generator can know the top bits are zero, not undefined.
Thanks to Dan for pointing this out.

9b099cf51b formatted_raw_ostream both is-a raw_ostream and has-a raw_ostream. This 
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.
