prefixes for other than FS/GS in 64-bit mode. If doing so at all, it

xmm/ymm registers are distinct. This patch adds code to check for this,
and at once eliminates a superfluous check for not using PC-relative
addressing for these instructions (the fact that an index register is
required here already excludes valid PC-relative addresses). The
severity of the resulting diagnostics can be controlled via command
line option or directive.

got treated identically to the ones in the base range, due to not
paying attention to the fact that reg_entry's reg_num field doesn't
fully specify the register number (reg_flags also needs to be checked
for RegRex). This patch introduces and uses a new (inline) function to
obtain the full register number, and uses it to fix all those cases.
It additionally adds the missing operand checks for SVME instructions
(which match the monitor/mwait ones).

If you configure gas for a mips32el-* target, the default cpu calculation
gets mangled, and we end up passing and invalid value as the default cpu.
If you try executing gas after that, it segfaults. This is because it
assumes that the default cpu value is always valid.
$ ./gas/as-new
Assembler messages:
Error: Bad value (2) for default CPU
Segmentation fault (core dumped)
I'm not debating that the target tuple is valid, just that gas shouldn't
crash. So add a friendly assert to avoid that.
