This commit improves bugpoints speed. On my G4 this changed caused kimwitu++ to run through bugpoint in 1091.15 seconds (user + system time). The time it took to run this on my G4 before I made these changes is 1420.82 seconds (user + system time). This is a speedup of about 5.5 minutes.

This is faster because SplitFunctionsOutOfModule no longer calls Clone Module and then removes the functions it doesnt want from the module returned. Instead it creates a module and copies over the specified functions, making changes to the new and old module where neccessary. This reduces the memory demand.

have a compile-host version of "nm", not build-host. In order to effect this
we must use autoconf to determine the correct "nm" to use and propagate that
through the makefiles, through llvm-config and finally to GenLibDeps.pl as
an optional argument.
Patch contributed by Anton Korobeynikov. Thanks!

cause LLVM to become a cross-compiler but rather cross-compile LLVM so that
it can execute on a platform other than the build host.

Remove NodeDepth; Add NodeId which is a unique id per node per DAG. It can only be set by SelectionDAG.
