2d32b86543 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

Fixes <rdar://problem/10140300>

62b2fea43d llvm-config-2: Implement component dependency traversal, implement support for 'all', and fix a few other minor bugs. 
- Still doesn't use actual generated component table, but that is now just a matter of wiring into the build system.

7fdd291c91 llvm-config: Start stubbing out a C++ version of llvm-config (as llvm-config-2, 
for now).

 - Mostly complete except for the data that needs to come from the build system
   or the dependencies.

 - Has some small improvements from current llvm-config:

   o Uses TargetRegistry directly to get some information.

   o Designed to work correctly when used from a CMake build tree (relatively
     untested currently) (although pcc fixed this recently for old llvm-config).

81550dc0a8 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.

05a484b909 Add back the top-level target for 'llvm-config' and the dependency edge 
to force it to build after all library targets so it has complete
dependency information. This should fix broken 'make install' with
CMake.

This is a partial revert of r143540, but it doesn't revert the most
important part of that change: removing the dependency edge from LLVM
tools to the llvm-config script.

d3714b60b5 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.

37efc9fe42 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.
