Qi Hu 1215317510 target/i386: Fix calculation of LOCK NEG eflags 
After:

        lock negl -0x14(%rbp)
        pushf
        pop    %rax

%rax will contain the wrong value because the "lock neg" calculates the
wrong eflags.  Simple test:

        #include <assert.h>

        int main()
        {
          __volatile__ unsigned test = 0x2363a;
          __volatile__ char cond = 0;
          asm(
              "lock negl %0 \n\t"
              "sets %1"
              : "=m"(test), "=r"(cond));
          assert(cond & 1);
          return 0;
        }
