target/i386: Remove obsolete TODO file 



The last real change to this file is from 2012, so it is very likely
that this file is completely out-of-date and ignored today. Let's
simply remove it to avoid confusion if someone finds it by accident.

Correctness issues:



- some eflags manipulation incorrectly reset the bit 0x2.

- SVM: test, cpu save/restore, SMM save/restore. 

- x86_64: lcall/ljmp intel/amd differences ?

- better code fetch (different exception handling + CS.limit support)

- user/kernel PUSHL/POPL in helper.c

- add missing cpuid tests

- return UD exception if LOCK prefix incorrectly used

- test ldt limit < 7 ?

- fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)

- full support of segment limit/rights 

- full x87 exception support

- improve x87 bit exactness (use bochs code ?)

- DRx register support

- CR0.AC emulation

- SSE alignment checks



Optimizations/Features:



- add SVM nested paging support

- add VMX support

- add AVX support

- add SSE5 support

- fxsave/fxrstor AMD extensions

- improve monitor/mwait support

- faster EFLAGS update: consider SZAP, C, O can be updated separately

  with a bit field in CC_OP and more state variables.

- evaluate x87 stack pointer statically

- find a way to avoid translating several time the same TB if CR0.TS

  is set or not.
