Disassemble more x86 instructions

By using oatdump on the core.oat, I found a couple more instructions
that didn't disassemble properly.  These included another form of imul
and some FP instructions used by the JNI code.

Now the only unknown opcodes I could find seem to be literal data at
the end of the method.
