Despite them being ignored by the CPU, gas issues segment override
prefixes for other than FS/GS in 64-bit mode. If doing so at all, it
should clearly do this correctly. Determining the default segment,
however, requires to take into consideration RegRex (so far, RSP, RBP,
R12, and R13 were all treated equally here).

The VGATHER group of instructions requires that all three involved
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

There were several cases where the registers in the REX encoded range
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.

(which match the monitor/mwait ones).
