88423eecd0 Split out the Dwarf writer stuff into separate files. This is a much more
logical/sane approach to organizing all of the stuff that goes into writing out
DWARF information. Honestly? even this is too complex for what it's supposed to
be doing.

Trivia: It *looks* like there would be functionality changes, however there aren't!

f59d10f1bc There's yet more ugliness (surprise!) in DebugInfo. This needs major reworking.
Basically, there was a situation where it was getting an empty vector and doing
a .back() on that. Which isn't cool.

df1ed67890 The IfConverter::MergeBlocks method appears to be used only to merge a basic
block with its unique predecessor.  Change the code to assert if that is not
the case, instead of trying to handle situations where the block has
multiple predecessors.

2afb3b7251 Removing the HasBuiltinSetjmp flag and associated bits. Flagging the presence
of exception handling builtin sjlj targets in functions turns out not to 
be necessary. Marking the intrinsic implementation in the .td file as 
defining all registers is sufficient to get the context saved properly by 
the containing function.

8308e8fae0 Revert a portion of Dan's change r71018 that I'm convinced is wrong.
Dan was trying to catch the case where a basic block ends with a conditional
branch to the fall-through block.  In this case, all the instructions have
been moved out of FromBBI, leaving it empty.  It cannot end with a
conditional branch.  As the existing comment indicates, it will always fall
through to the next block.  If the block already had the next block (NBB)
listed as a successor, the preceding loop has a check for that and does not
remove it.  Thus, we need to check and add the successor only when it is
not already listed.

With Dan's change, the empty block often ends up with the fall-through
successor listed twice.  This exposed the problem in pr4195, where
CodePlacementOpt did not handle the same predecessor listed more than once.
It is also at least partially responsible for pr4202 and probably a similar
issue with Thumb branches being out of range.

587daedce2 Change MachineInstrBuilder::addReg() to take a flag instead of a list of
booleans. This gives a better indication of what the "addReg()" is
doing. Remembering what all of those booleans mean isn't easy, especially if you
aren't spending all of your time in that code.

I took Jakob's suggestion and made it illegal to pass in "true" for the
flag. This should hopefully prevent any unintended misuse of this (by reverting
to the old way of using addReg()).
