In commit
9bb987d8e0330429afba42015b1fc7c7ca0d1b16
we had to drop some flags due to flags type used
in nasm code.
Since now flags internal structure is reworked, we
can restore them back.

insns: Introduce insns-flags.pl
It been found that 64 bits for instruction flags is too small,
so instead we start using indirect addressing scheme to keep
instruction flags in bitvectors instead.
Using one bitvector per instruction template entry is wastefull
(especially if vector grow in future, at moment it's 128 bit length),
so we use indirect addressing, which is generated as follow
- read instruction flags from insns.dat
- flag sequence sorted and joined into one key string
- this key string become a hash index
- all hash entries are compacted into one array
- every instruction template uses array offset instead
of flags bitfield
Just for info, at moment we have 195 unique flags combination,
but since instruction template will use index as unsigned
integer, we can use a way more wider combination of flags
in future.

bnd: Drop bnd prefix for relaxed short jmp instructions
Reverted the redundant branch instruction patterns for bnd prefix.
And when a relaxed jmp instruction becomes a short (Jb) form,
bnd prefix is not needed because it does not initialize bnd registers.
So in that case, bnd prefix is silently dropped.
BND JMP foo -> drops bnd prefix
BND JMP short foo -> shows an explicit error
