x86_32: handle x87 opcodes in TLS segment fixups
This patch adds support to the TLS fixup code for x87 opcodes. These
can be treated like 2-byte opcodes with a weird encoding.
The patch includes some extra changes because, now that we have >2
opcode tables and 9 different lead bytes in a two-byte opcode, a
simple boolean code will not be enough to differentiate one- and
two-byte opcodes. Besides this, the patch is trivial since the
segment fixup code cares about the operands of the instruction, not
about its semantics.
