optim: split the Taylor series calculation into two separate values.
This is at the cost of one additional multiply, but performance increases
by more than 11%, because the PS3 pipeline is a lot happier now.

core: minor optimisation in the x86 version of lol_sin()
Instead of dividing by 2 and rounding with magic number 2^52, we round with
magic number 2^53, which gives us the parity with at least one mul less.

test: implement a custom isnan()
This version is faster (about 25% on x86_64) and works when extreme
optimisation options such as -ffast-math are used.

core: reactivate half denormals for the PS3.
We know we will not have denormal floats on the PS3, but we should still
create denormal halves in case the other end (maybe the GPU?) knows how
to handle them.

contrib: rebuild the Win32 CppUnit under Linux and fix the includes.
Apparently g++ 4.5.2 on native mingw32 inserts references to __Unwind_Resume
when exceptions are supported. This function is not present in the g++ 4.4
cross-compiler found in Debian, leading to linker errors when cross-
compiling. So we use the latter to build CppUnit itself.
Another problem arises with g++ 4.4, which is the incomplete stripping of
exceptions when -fno-exceptions is used. Since ExceptionTestCaseDecorator.h
has such code, we protect it with #ifdef __EXCEPTIONS in the meantime.
