  - Make targetlowering.h fit in 80 cols.
  - Make LowerAsmOperandForConstraint const.
  - Make lowerXConstraint -> LowerXConstraint
  - Make LowerXConstraint return a const char* instead of taking a string byref.

Added improved diagnostics for break and continue statements and default branches in switch statements.

This fixes <rdar://problem/5889244>.

to the block that defines their operands. This doesn't work in the
case that the operand is an invoke, because invoke is a terminator
and must be the last instruction in a block.

Replace it with support in SelectionDAGISel for copying struct values
into sequences of virtual registers.

idea what this code (findNonImmUse) does, so I'm only guessing 
that this is the right thing.  It would be really really nice
if this had comments and perhaps switched to SmallPtrSet
(hint hint) :)

  Threading edge through bool from 'bb37.us.thread3829' to 'bb37.us' with cost: 1, across block:
