[gdb/testsuite] Fix gdb.reverse/insn-reverse-x86.c for -m32
When running test-case gdb.reverse/insn-reverse.exp with target board
unix/-m32, we get:
...
spawn -ignore SIGHUP gcc -fno-stack-protector -fdiagnostics-color=never \
-c -g -m32 -o insn-reverse0.o insn-reverse.c^M
insn-reverse-x86.c: Assembler messages:^M
insn-reverse-x86.c:88: Error: bad register name `%r8w'^M
....
Fix this by guarding x86_64 assembly in insn-reverse-x86.c with #ifdef
__x86_64__.
Tested on x86_64-linux, with native and unix/-m32.

* gdb.reverse/insn-reverse-x86.c: Guard x86_64 assembly with #ifdef
__x86_64__.
