SH4: Implement FD bit

SH4 manual say that if a floating point instruction is executed while
FD bit in the status register is 1, an exception should be raised. QEMU
presently does not do that, so the kernel does not initialize FP state
for any thread, nor does it save/restore FP state. The most apparent...

SH4: Eliminate P4 to A7 mangling (Takashi YOSHII).

Main purpose of this is to delete
*physical = address & 0x1fffffff;

This masking is a nice trick to realize P4/A7 duality of SH registers....

Common cpu_loop_exit prototype

All archs use the same cpu_loop_exit, so move the prototype in a common
header. i386 was carrying a __hidden attribute, but that was empty for
this arch anyway.
