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.

Generally, remove use of fork/exec from bugpoint in favor of the portable
sys::Program::ExecuteAndWait method. This change requires two new options
to bugpoint to tell it that it is running in "child" mode. In this mode,
it reads its input and runs the passes. The result code signals to the
parent instance of bugpoint what happened (success, fail, crash).
This change should make bugpoint usable on Win32 systems.

This patch adds a -post-link-opts option to llvm-ld which allows an arbitrary
program to optimize bytecode after linking. The program is passed two file
names. The first is the input (linked bytecode) the second is where it must
place its output (presumably after optimizing). If the output file is bytecode,
it is used as a substitute for the input. This will allow things like poolalloc
to be written as a separate program instead of a loadable module or built into
LLVM.

pointer marking the end of the list, the zero *must* be cast to the pointer
type. An un-cast zero is a 32-bit int, and at least on x86_64, gcc will
not extend the zero to 64 bits, thus allowing the upper 32 bits to be
random junk.
The new END_WITH_NULL macro may be used to annotate a such a function

Instead of emitting a JIT stub that looks like this:

%resolverCast = cast sbyte* %resolver to void (int)* ; <void (int)*> [#uses=1]
call void %resolverCast( int %0 )
ret void

Emit one that looks like this:
internal void %l1_main_entry_2E_ce_wrapper(int) {
Entry:

This makes the JIT debugger *MUCH* faster on large programs, as
getPointerToNamedFunction takes time linear with the size of the program, and
before we would call it every time a function in the text module was called from
the safe module (ouch!).

This chagne just renames some sys::Path methods to ensure they are not
misused. The Path documentation now divides methods into two dimensions:
Path/Disk and accessor/mutator. Path accessors and mutators only operate
on the Path object itself without making any disk accesses. Disk accessors
and mutators will also access or modify the file system. Because of the
potentially destructive nature of disk mutators, it was decided that all
such methods should end in the work "Disk" to ensure the user recognizes
that the change will occur on the file system. This patch makes that
change. The method name changes are:
makeReadable -> makeReadableOnDisk
makeWriteable -> makeWriteableOnDisk
makeExecutable -> makeExecutableOnDisk
setStatusInfo -> setStatusInfoOnDisk
createDirectory -> createDirectoryOnDisk
createFile -> createFileOnDisk
createTemporaryFile -> createTemporaryFileOnDisk
destroy -> eraseFromDisk
