Adjust the slot machine to handle Types separately from Values. This was
...
done by doubling up the data structures so that Type based equivalents are
used. A consequence of this is overloading of function members that take a
Type* instead of a Value*. Various other cleanups related to Type != Value
(bug 122) were also implemented.

For bug 122:
...
Separate Types from Values because Type no longer inherits from Value. The
changes for this are too numerous to list. In essence, any data structure
that contained a Value was doubled so that Types could be contained
similarly. New members include Types, TypeMap, CompactionTypes, and
CompactionTypeMap. Functions taking a Value* were overloaded with a variant
that takes a Type* that acts on the new data structures.

select blocks that are unreachable. Until we have a instruction selection
framework available for use, however, we can't expect all instruction
selector writers to do this. Until then, this pass should be used.

Do not let the numbering of PHI nodes placed in the function depend on
...
non-deterministic things like the ordering of blocks in the dominance
frontier of a BB. Unfortunately, I don't know of a better way to solve
this problem than to explicitly sort the BB's in function-order before
processing them. This is guaranteed to slow the pass down a bit, but
is absolutely necessary to get usable diffs between two different tools
executing the mem2reg or scalarrepl pass.
Before this, bazillions of spurious diff failures occurred all over the
place due to the different order of processing PHIs:
- %tmp.111 = getelementptr %struct.Connector_struct* %upcon.0.0, uint 0, uint 0
+ %tmp.111 = getelementptr %struct.Connector_struct* %upcon.0.1, uint 0, uint 0
Now, the diffs match.

Do not sort by the address of LLVM ConstantInt* objects. This produces

nondeterministic results that depend on where these objects land in memory.
Instead, sort by the value of the constant, which is stable.
Before this patch, the -simplifycfg pass run from two different compilers
could cause different code to be generated, though it was semantically the
same:
