Step in removing CC_OP: change the representation of CC_OP_FLAGS.
The 8 bits are distributed between 6 variables, which should make
it easy to keep up to date.
The code within cc_helper.c is quite ugly but is only temporary.

The oldest supported cpu is the microsparc 1; all other cpus
use CPU_DEFAULT_FEATURES. Remove the features that must always
be present for sparcv7: FLOAT, SWAP, FLUSH, FSQRT, FMUL.

Move the various open_cpuinfo functions into new files.
Move the m68k open_hardware function as well.
All other guest architectures get a boilerplate empty file.

For the most part priviledged opcodes are ifdefed out of the
user-only sparc translator, which will then incorrectly produce
illegal opcode traps. But there are some code paths that
properly raise TT_PRIV_INSN, so we must handle it.

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.

Use TT_TRAP.
For sparc32, 0x88 is the "Slowaris" system call, currently BAD_TRAP
in the kernel's ttable_32.S. For sparc64, 0x110 is tl0_linux32, the
sparc32 trap, now folded into the TARGET_ABI32 case via TT_TRAP.
For sparc64, there does still exist trap 0x111 as tl0_oldlinux64,
which was replaced by 0x16d as tl0_linux64 in 1998. Since no one
has noticed, don't bother implementing it now.

The linux kernel's trap tables vector all unassigned trap
numbers to BAD_TRAP, which then raises SIGILL.
