efffdc9408 As much as I hate to say it, the whole setNode interface for DSNodeHandles
is HOPELESSLY broken.  The problem is that the embedded getNode call can
change the offset of the node handle in unpredictable ways.

As it turns out, all of the clients of this method really want to set
both the node and the offset, thus it is more efficient (and less buggy)
to just do both of them in one method call.  This fixes some obscure bugs
handling non-forwarded node handles.

d18a31d2fa * Add support for calling vararg functions (must pass doubles in int regs too)
* Make visitSetCondInst() share condition-generating code with EmitComparison()

* Do not rely on registers being sequential, use an array lookup

  fall-through
* Add doInitialization() for adding function prototypes for external math fns
* Minor changes: fix indentation, spacing, code clarity

0e25e1cdcf 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

(bug 122) were also implemented.

24ab28f1e5 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.

fc3c82a804 Add a trivially simple pass to delete unreachable blocks from the CFG. This
pass is required to paper over problems in the code generator (primarily
live variables and its clients) which doesn't really have any well defined
semantics for unreachable code.

The proper solution to this problem is to have instruction selectors not
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.
