Add support for passing i1, i8, and i16 call parameters.  Also, be sure to

When materializing an i32, SExt vs ZExt doesn't matter when we're trying to fit
in a 16-bit immediate.  However, for the shorter non-legal types (i.e., i1, i8,
i16) we should not sign-extend.  This prevents us from materializing things
such as 'true' (i.e., i1 1).

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

llvm-build: Validate information on the loaded components and form the topological ordering among them (as well as validating that there are no cycles).
 - Currently we require that all references between components (except the parent relation) fit into a DAG -- this could be relaxed later if it ever proves to be useful.

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.

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).
