Richard Henderson	4aa3f4dd5b	linux-user: Fix i386 safe-syscall.S Clang insists that "cmp" is ambiguous with a memory destination, requiring an explicit size suffix. There was a true error in the use of .cfi_def_cfa_offset in the epilogue, but changing to use the proper .cfi_adjust_cfa_offset runs afoul of a clang bug wrt .cfi_restore_state.

linux-user: Fix i386 safe-syscall.S

Clang insists that "cmp" is ambiguous with a memory destination,
requiring an explicit size suffix.

There was a true error in the use of .cfi_def_cfa_offset in the
epilogue, but changing to use the proper .cfi_adjust_cfa_offset
runs afoul of a clang bug wrt .cfi_restore_state.  Better to
fold the two epilogues so that we don't trigger the bug.
