[PATCH 1/9] target/i386: silence the compiler warnings in gen_shiftd_rm_T1

[Chen Qun]

The current "#ifdef TARGET_X86_64" statement affects
the compiler's determination of fall through.

When using -Wimplicit-fallthrough in our CFLAGS, the compiler showed warning:
target/i386/translate.c: In function ‘gen_shiftd_rm_T1’:
target/i386/translate.c:1773:12: warning: this statement may fall through 
[-Wimplicit-fallthrough=]
         if (is_right) {
            ^
target/i386/translate.c:1782:5: note: here
     case MO_32:
     ^~~~
