(FIND) ( -- rec | 0 ), (DEFINE) ( value kind -- ) and (OPCODE) ( -- op | -1 ),
entries 3-5. Names are refused as text.c's define refuses them, compared
case by case with text.c; a set variable may be set again. 256 hash heads,
records growing up and names growing down in dictionary space, used only
while the ROM assembles. text.c gains the data directives #, and ", (the
ROM's language; its mnemonic and reserved-word tables are data); the
nucleus image is byte-identical.

The ROM's source is F18 code in capsules/v4/rom, assembled off the node by
v4/tools/mkrom.c with the memory map's constants from v4/tools/mkmap.c
(MACHINE.md 2). main.f18 is the entry table payloads call through (2.1);
in.f18 reads the console and splits it into tokens exactly as text.c does,
the token held packed as a counted string. The ROM's state is a reserved
area of the map (host_map.h ROM_*). text.c gains the constant directive,
so the off-node assembler and the ROM speak one language. The map also
names (NUMBER)'s state, for the next task.

&NAME is the address of a word as a literal; CONST+N is a loader
constant plus an offset as one literal, so that a capsule file can
address the cells of its scratch area without adding at run time.

'header NAME [flags]' in front of a word gives it a dictionary entry in
the layout capsule/dict.v4 uses, linked to the header before it, so the
words of a capsule are in the dictionary as soon as it is assembled.
The name is taken as it stands (it may be ( or + or ;) and the
assembler's own name for the code may differ.
Tested in the assembler's own test, and by FIND and the field words
running over assembler-made entries beside ones (HEADER) made.

Test support, beside the slot packer: reads definitions in the notation
DECOMPOSITION.md uses -- words, opcodes, literals, constants, labels,
branches, FOR NEXT and FOR UNEXT, in-line macros, comments -- and lays
them down through the slot packer, so they no longer have to be retyped
opcode by opcode in C.
Tested by assembling SWAP, UM/MOD, C@ and C! both ways on two nodes and
comparing memory word for word, by running what is assembled, and on
every error it reports, each with its line number.
