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()
* There are 13 FPRs for function-passing arguments, not 8
* Do not rely on registers being sequential, use an array lookup
* In unimplemented switch cases, send an error and abort instead of silent
  fall-through
* Add doInitialization() for adding function prototypes for external math fns
* Minor changes: fix indentation, spacing, code clarity

ebeebecad2 Change the "rotate by 90" xtics specification to just "rotate" which is
equivalent. The "by <angle>" syntax is not acceptable for all output
devices. Apparently the Sparc and x86 output devices (no color) don't
accept this, but should accept the plain "rotate".

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.
