SPDX is an international standard for documenting software license
requirements. Remove the existing headers and replace with a brief
SPDX preamble.
See: https://spdx.dev/use/specifications/
The script used to convert the files is added to "tools", and the
file header templates in headers/ are updated.

Strip all whitespace from version.pl input, in case combinations of
tools causes stray \r or other whitespace characters (which has been
observed.)

Don't redo the whole clone and compile if one wants to re-run the
test. Only rebuild the NASM files.
Minor script cleanups.

Error out if an encoding position is invalid, like an "r" operand
matches an "xmmrm" operand.
Document the instruction encoding symbols; there are too many of them
by now.
Add symbols 'n' and 'w' meaning immediates that are supposed to be
encoded as if they were 'm' memory addresses and 'v' register numbers,
respectively; this is necessary to indicate a validation exception.
Remove broken ARPL "memory-like" encoding. It probably never worked
anyway.
This verification caught two bugs already:
- VPMASKMOV[DQ] cannot omit the second operand.
- Incorrect operand encoding order for VREDUCESH.

Add missing uses of PRI constants.
Create a PRI constant for size_t, since %z isn't available on all
platforms. Notably, the legacy Windows runtime needs %I instead of %z.
Use that on UCRT as well, since there doesn't seem to be a way to
determine if you are compiling for MSVCRT or UCRT.

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

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