Move the DUMP_FPU and DUMP_CCOP flags for cpu_dump_state() from being
x86-specific flags to being generic ones. This allows us to drop some
TARGET_I386 ifdefs in various places, and means that we can (potentially)
be more consistent across architectures about which monitor commands or
debug abort printouts include FPU register contents and info about
QEMU's condition-code optimisations.

Reinstate the display of VFP registers in cpu_dump_state(), if
the CPU has them (this code had been #if 0'd out a for a long time).
We drop the attempt ot display the values as floating point, since
this makes assumptions about the host 'float' and 'double' formats
and is not done by eg the i386 cpu_dump_state().
This display is gated on the CPU_DUMP_FPU flag, as for x86.
