Varargs is apparently currently broken on PPC. This hacks it so that it

is at least overloading the right virtual methods. The implementations
are currently wrong though. This fixes Ptrdist/bc, but not other programs
(e.g. siod).

Basic fix for PR#591; don't convert an fprintf() to an fwrite() if there
...
is a mismatch in their character type pointers (i.e. fprintf() prints an
array of ubytes while fwrite() takes an array of sbytes).
We can probably do better than this (such as casting the ubyte to an
sbyte).

Initial set of .td file changes necessary to get scalar fp in xmm registers

working. The instruction selector changes will hopefully be coming later
this week once they are debugged. This is necessary to support the darwin
x86 FP model, and is recommended by intel as the replacement for x87. As
a bonus, the register allocator knows how to deal with these registers
across basic blocks, unliky the FP stackifier. This leads to significantly
better codegen in several cases.
