succinct. Added a section to Describe the notation, made the VBR
description its own section, and otherwise generally cleaned things up.

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.

* 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

Don't touch GEPs for which DecomposeArrayRef is not going to do anything

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".

Also, remove X % -1 = 0, because it's not true for unsigneds, and the
signed case is superceeded by this new handling.

basic block clear()'s all of the operands lists, including phis.  This
caused removePredecessor to get confused later.  Because of this, we just
nuke (without prejudice) PHI nodes in unreachable blocks.
