target/sparc: Remove old TODO file

This file hasn't seen a real (non-trivial) update since 2008 anymore,
so we can assume that it is pretty much out of date and nobody cares
for it anymore. Let's simply remove it.

-TODO-list:
-
-CPU common:
-- Unimplemented features/bugs:
- - Delay slot handling may fail sometimes (branch end of page, delay
- slot next page)
- - Atomical instructions
- - CPU features should match real CPUs (also ASI selection)
-- Optimizations/improvements:
- - Condition code/branch handling like x86, also for FPU?
- - Remove remaining explicit alignment checks
- - Global register for regwptr, so that windowed registers can be
- accessed directly
- - Improve Sparc32plus addressing
- - NPC/PC static optimisations (use JUMP_TB when possible)? (Is this
- obsolete?)
- - Synthetic instructions
- - MMU model dependent on CPU model
- - Select ASI helper at translation time (on V9 only if known)
- - KQemu/KVM support for VM only
- - Hardware breakpoint/watchpoint support
- - Cache emulation mode
- - Reverse-endian pages
