81d4e14449 When internalizing global ctor/dtor list, also mark it constant. This is gross, but 
until DSA is working all of the time and is totally reliable, we do this.

dc52353833 Run the simplify CFG pass after instcombine which has the effect of deleting 
ALL of the global ctor/dtor stuff if it is not used!

Shootout, but it has some issues with bigger programs. Work in progress.

54f6032dae - Fixed name mangling conditions to handle 'linkonce' linkage type. In 
particular, name mangling for GlobalValues only occurs when the linkage type is
internal or when the name must be mangled to avoid a collision.  See comments in
CWriter::getValueName for more information.

- 'inline' keyword is now emitted for functions with 'linkonce' linkage type.

- Fixed typos.

e99f4cf4ac It seems likely that floats would need a cast too, because they are 
ordinarily promoted to doubles.

99c91e021a Do not mark ALL terminators live if any instruciton in the block is live. We only 
want to mark it live if it is an unconditional branch.  This fixes bug:
ADCE/2002-05-28-Crash.ll and makes this pass _much_ more useful.
