Remove use of global register A0 (now aliased to T0). This makes it possible

to cache the CPU context pointer to a register and thus rendering generated

(and even improved) in the future.

Improve FPU emulation accurracy. However, PPC_ENABLE_FPU_EXCEPTIONS is still
...
set to 0 until generated code is optimized enough (current slow down factor
is 3x vs. previous core, expectations are about 50% slower FP code).
The main benefit is exception bits are accurate. All glibc test-fenv,
test-arith{,f}, test-double, test-float pass on ppc, and mostly on x86_64
with gcc 4.0.1. Yes, this is also compiler dependent.
FIXME: find a real Mac application that depends on precise FPSCR bits... I
think I don't want to care optimizing yet until someone shows me a real world
application.
