Currently these are implemented as a separate pass guarded by a separate

statistics for the old code placement as well as the new in order to
have a point of comparison. I'm planning on folding them into the single
pass if / when there is only one pass of interest.

Add support to the linker to lazily link in functions. This change only links functions marked with specific linkage (internal, private, linker_private, linker_private_weak, linker_private_weak_def_auto, linkonce, linkonce_odr, and available_externally) if they have uses in the destination module. Instead of automatically linking, these functions are placed onto a worklist to be processed in the final stage of linking. We iterate over the list and if any functions on the list have uses in the destination module, we link them in and repeat the process until no changes in the state (uses) has changed. This means that any functions in the LazilyLink worklist that have a use in the destination module will be linked in and none that don't.

Fixed a bug in the code to create a dwarf file and directory table entires when

it is separating the directory part from the basename of the FileName. Noticed
that this:
.file 1 "dir/foo"
when assembled got the two parts switched. Using the Mac OS X dwarfdump tool
it can be seen easily:

include_directories[ 1] = 'foo'
Dir Mod Time File Len File Name
---- ---------- ---------- ---------------------------
file_names[ 1] 1 0x00000000 0x00000000 dir

Which should be:

include_directories[ 1] = 'dir'
