the end of it is dead.", which appears to break bootstrapping LLVM.

a5f382da8b Reapply r143206, with fixes. Disallow physical register lifetimes 
across calls, and only check for nested dependences on the special
call-sequence-resource register.

4902705b5f DeadStoreElimination can now trim the size of a store if the end of it is dead. 
Only currently done if the later store is writing to a power of 2 address or 
has the same alignment as the earlier store as then its likely to not break up
large stores into smaller ones

ac9fd95057 Fix the issue that r143552 was trying to address the _right_ way. One-register lists are legal on LDM/STM instructions, but we should not print the PUSH/POP aliases when they appear. This fixes round tripping on this instruction.

3c1e831108 Rewrite LinearFunctionTestReplace to handle pointer-type IVs. 
We've been hitting asserts in this code due to the many supported
combintions of modes (iv-rewrite/no-iv-rewrite) and IV types. This
second rewrite of the code attempts to deal with these cases systematically.

f95461f23b Begin collecting some of the statistics for block placement discussed on 
the mailing list. Suggestions for other statistics to collect would be
awesome. =]

Currently these are implemented as a separate pass guarded by a separate
flag. I'm not thrilled by that, but I wanted to be able to collect the
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.

81f9010d3a 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.

b5dc88b394 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:

% dwarfdump -a a.out
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'
                Dir  Mod Time   File Len   File Name
                ---- ---------- ---------- ---------------------------
file_names[  1]    1 0x00000000 0x00000000 foo

64fe093030 First part of support for generating dwarf for assembly source files with the 
-g flag.  In this part we generate the .file for the source being assembled and
the .loc's for the assembled instructions.

The next part will be to generate the dwarf Compile Unit DIE and a dwarf
subprogram DIE for each non-temporary label.

Once the next part is done test cases will be added.  rdar://9275556
