[Bug target/42165] New: -masm=intel doesn't know how to print AVX instructions

[matti dot niemenmaa+gccbugs at iki dot fi]

Using -masm=intel and -mavx together with something that uses a 256-bit vector
causes an internal error:

$ gcc arst.c -mavx -masm=intel
arst.c: In function ‘foo’:
arst.c:2: internal compiler error: in print_operand, at
config/i386/i386.c:11324

$ cat arst.c
typedef unsigned long vec __attribute__((vector_size(32)));
void foo(vec a) {}

$ gcc -v
Using built-in specs.
