Log Message:
-----------
Update i386-dis.c from commits before GPLv3 switch

Update i386-dis.c again using binutils files from CVS:
include/opcode/i386.h r1.78 and opcodes/i386-dis.c r1.126.

These are the last versions using GPL v2+.

+/* The SystemV/386 SVR3.2 assembler, and probably all AT&T derived
+   ix86 Unix assemblers, generate floating point instructions with
+   reversed source and destination registers in certain cases.
+   Unfortunately, gcc and possibly many other programs use this
+   reversed syntax, so we're stuck with it.
+
+   eg. `fsub %st(3),%st' results in st = st - st(3) as expected, but
+   `fsub %st,%st(3)' results in st(3) = st - st(3), rather than
+   the expected st(3) = st(3) - st
+
+   This happens with all the non-commutative arithmetic floating point
+   operations with two register operands, where the source register is
+   %st, and destination register is %st(i).
+
+   The affected opcode map is dceX, dcfX, deeX, defX.  */
