Bill Wendling 523048ecde Split the addPassesToEmitFile method up into two. This is so that we can 
do some common stuff, then on our own add an object file writer (by calling
a concrete function), and then do some finishing stuff, if need be.

Jim Laskey 6ea4fae838 1. Add a pass to fold debug label instructions so a debug info client can detect 
empty ranges.

2. Reorg how MachineDebugInfo maintains changes to debug labels.

3. Have dwarf writer use debug label info to simplify scopes and source line
coorespondence.

4. Revert the merging of compile units until I can get the bugs ironed out.

Chris Lattner 55ad08a59b add the branch folding pass as a late cleanup pass for all targets. For now 
it just deletes empty MBB's.  Soon it will do more :)

Duraid Madina cf6749e4c0 add setJumpBufSize() and setJumpBufAlignment() to target-lowering. 
Call these from your backend to enjoy setjmp/longjmp goodness, see
lib/Target/IA64/IA64ISelLowering.cpp for an example
