Preserve AR.FPSR in thread context

AR.FPSR is a preserved register so it should be part of the thread
context, leaving its extra copy in istate_t rather for debugging
purposes.

In this commit we also disable all IEEE FP traps and the
Denormal/Unnormal Operand Floating-Point Exception fault for each new
thread context, leaving the thread with the possibility to change this
setting later in uspace.
