x86/gas: replace inappropriate assertion when parsing registers
PR gas/30117
Once a symbol had its expression evaluated, the "segment" of the symbol
may be reg_section if a register is merely involved in the expression,
not just when the expression references a "plain" register. Therefore
the first of the assertions put in place by 4d1bb7955a8b was too strict.
Convert it to an if() to deal with situations like this one found by
fuzzing:
x=s
s=%eax+0
y=s
or $6,x
In non-debug builds this also avoids potentially silently generating bad
code.
