Move target-* CPU file into a target/ folder
We've currently got 18 architectures in QEMU, and thus 18 target-xxx folders in the root folder of the QEMU source tree. More architectures (e.g. RISC-V, AVR) are likely to be included soon, too, so the main folder of the QEMU sources slowly gets quite overcrowded with the target-xxx folders. To disburden the main folder a little bit, let's move the target-xxx folders into a dedicated target/ folder, so that target-xxx/ simply becomes target/xxx/ instead.

+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.
