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.

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.

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.

eeff2524ce Verify that there is no kill flag on tied operands on two-address instructions. 
This extra check is not trigged when runnning "make check" on top-of-tree.

Change error message to better match llvm_unreachable() grammar.

Don't call llvm_unreachable() when writing error messages to a file, but keep going.

f01e53a482 Change raw_ostream so that it doesn't call llvm_report_error 
immediately on every output error. Instead, add a flag to
raw_ostream, and set the flag whenever an error is detected.

The flag can be queried and cleared from the public API. This
gives applications more flexibility to handling errors in
application-specific ways.

If the flag is not cleared when the raw_ostream is destructed,
llvm_report_error is called from the destructor. This ensures
that errors are not implicitly silenced, and provides
convenient default behavior for tools like llc and opt.
Clients wishing to avoid llvm_report_error calls from
raw_ostream should check for errors and clear the error flag.
