-linux-user: incorrect alignment of sigframe::pretcode & rt_sigframe::pretcode cause crash
-Description of problem:
-Corrent Print Result:
-
-sp: cdd3b4e8
-
-SUCCEEDED!
-
-qemu-x86_64 Print Result:
-
-sp: 2804170
-
-qemu: uncaught target signal 11 (Segmentation fault) - core dumped
-
-Segmentation fault
-
-Reason of Bug:
-
-sigframe::pretcode & rt_sigframe::pretcode must align of 16n-sizeof(void*) instead of 16n, Because rsp align of 16n before instruction "call" in caller, After "call", push address of "call" in caller. sp of begin in callee is 16n-sizeof(void*)
-
-For example on x86_64:
-
-reference to "qemu/linux-user/i386/signal.c"
-
-```
-# define TARGET_FPSTATE_FXSAVE_OFFSET 0
-
-struct rt_sigframe {
-    abi_ulong pretcode;
-    struct target_ucontext uc;
-    struct target_siginfo info;
-    struct target_fpstate fpstate QEMU_ALIGNED(16);
-};
-#define TARGET_RT_SIGFRAME_FXSAVE_OFFSET (                                 \
-    offsetof(struct rt_sigframe, fpstate) + TARGET_FPSTATE_FXSAVE_OFFSET)
-```
-
-offsetof(struct rt_sigframe, fpstate) align of 16
-
-TARGET_FPSTATE_FXSAVE_OFFSET is 0
-
-TARGET_RT_SIGFRAME_FXSAVE_OFFSET is 16n, also alignment of fxsave is 64
-
-so address of rt_sigframe::pretcode is 16n instead of 16n - sizeof(void*), It is incorect!
-
-Fix the bug:
-
-```
-struct rt_sigframe {
-    abi_ulong pretcode;
-    struct target_ucontext uc;
-    struct target_siginfo info;
-    abi_ulong unused QEMU_ALIGNED(16);
-    struct target_fpstate fpstate;
-};
-```
-
-offsetof(struct rt_sigframe, fpstate) is 16n+8, so address of rt_sigframe::pretcode is 16n-8 on x86_64.
