Owen Anderson f7ebea1b9f Add DomSet back, and revert the changes to LoopSimplify. Apparently the
ETForest updating mechanisms don't work as I thought they did.  These changes
will be reapplied once the issue is worked out.

Reid Spencer 33766f8eba For PR1312:
For the short CALL/INVOKE syntax, the signedness of the result type is two
extractions away from the type argument because its a POINTER to function
type, not a function type.

Chris Lattner 5247f60d20 rearchitect the registration mechanism used by the command line option stuff.
This dramatically reduce the amount of memory allocated by the commandline stuff
at static init time, changing it to build local data structures when ParseCommandLineOptions
is called.  In a dummy empty program that links some llvm libraries, this reduces
the number of malloc'd bytes from 4864 to 3360 on entry to main.  Most of that
memory is now allocated by non-commandline related stuff.
