decode: Store op types early and compact encoding
...
* The encoding of operand types in the decode table now only requires 9
bits instead of the previous 16 bits.
* Operand types are decoded before the operands itself are stored. This
allows to ignore REX.RB prefixed for specific register types.

fadec: Make memory displacement 64-bit large
...
While for almost all instructions the memory address displacement is
sign-extended 32-bits (like for immediate operands), there is a single
case where this is not true: the FD/TD mov encoding allows for a 64-bit
memory address to be specified.
