The assembler can't know if something is a colonless label or a
misspelled instruction, so print both when complaining about a missing
instruction.

For disassembler to work correctly NOPs should be at the very end of the

Start the subchapter on jmp and call syntax summary. Move the far call

Add a couple of paragraphs about possible syntaxes of the jump/call
instructions.

The syntax chapter is supposed to be about concepts or instructions that
either have a lot of different syntaxes or new/odd ones.

- Fix additional broken rules
- Add some more files to WARNOBJ
- $^ is not supported by POSIX, apparently
- Update warnings.pl to *actually* use the srcdir and list of
passed-in files.

Make a note about the availability of the cccl wrapper for building
with MSVC using GNU make.
Minor tidying up of the building from source section in general.

It isn't actually required to have $(PERLREQ) to run syncfiles,
so factor it out into a separate target.

Using '' filename protects break the generated alternative makefiles,
but it is also largely useless -- building in relative paths which
require escaping breaks anyway as make and the shell would require
different escaping.

ISO C before C23 restricted enum ranges to type "int" (not even
"unsigned int"). This limits the usability of enums for bit fields,
but it still covers our main use cases.
On gcc/clang this just produces a warning, but who knows what other
compilers will do.

The MMX and early SSE PSHUF* instructions were annotated SM0-1, which
is unnecessary (no ambiguity) but broke the tighter SM matching the
assembler now uses.
This is almost certainly underspecified now, but the MMX and early SSE
instruction patterns need to be tidied up anyway, and this is the
least impactful change that seems to fix the problem.
This unbreaks compiling ffmpeg.

to make it easier to maintain this file.
