At least three files (asm/assemble.c, disasm/disasm.c, and
x86/insns.pl) depend on the bytecode defintions. It makes a lot more
sense for them to live in an explicit documentation file in the x86/
directory.

Instead of handling conditional instructions ad hoc, generate
individual instruction patterns as normal. This simplifies the code
and makes CMPccXADD support simpler (otherwise it would be necessary
to hack in the handling of a condition code in the middle of an
instruction.)

The FP16 patch had a case of bit overlap. Clean up the handling of
broadcast flags a little in the process.

Add support for AVX512-FP16 instructions and the associated
handling. Allow "mapN" syntax as well as "mN" syntax to match the
documentation.

"compiler.h" already includes a bunch of common include files. There
is absolutely no reason to duplicate them in individual files, and in
fact it robs us of central control of how these files are used.

There is absolutely no reason not to include <string.h> globally, and
with the inline function for mempcpy() we need it there anyway.

Support the +n syntax for multiple contiguous registers, and emit it
in the output from ndisasm as well.

This fixes disassembly of instructions like jmp/call when target address
is larger than 2^32-1, and also printing of current address when it's
large.
After this change ndisasm still assumes that the files to disassemble
will never reach 4GiB: only offsets are made 64 bit, but not lengths.

Make the source code easier to understand and keep track of by
organizing it into subdirectories depending on the function.
