These are really only meaningful for sparc32, but they're
still present for backward compatibility for sparc64.

Raise SIGFPE for ieee exceptions.
The other types, such as FSR_FTT_UNIMPFPOP, should not appear,
because we enable normal emulation of missing insns at the
start of sparc_cpu_realizefn().

Add some macros to localize the hw difference between v9 and pre-v9.

For sparc64, TT_UNIMP_FLUSH == TT_ILL_INSN, so this is
already handled. For sparc32, the kernel uses SKIP_TRAP.

Since qemu does not implement a sparc coprocessor, all such
instructions raise this trap. Because of that, we never raise
the coprocessor exception trap, which would be vector 0x28.

These traps are present for sparc64 with ilp32, aka sparc32plus.
Enabling them means adjusting the defines over in signal.c,
and fixing an incorrect usage of abi_ulong when we really meant
the full register, target_ulong.

In addition to the hw trap vector, there is a software trap
