The canonical form splits a label from the instruction that follows it,
but an identifier naming a macro may expand into any token at all: moved
to a line of its own it no longer parses, because the parser accepts a
non-mnemonic first token only behind a label. The names #define'd in
the file now hold such content back, conservatively across the whole
file, and the crashing input joins the corpus.

A label whose name is a macro expands into whatever the body is, so the
line's statement structure exists only after expansion; splitting the
label off changed clean input into a different statement sequence. The
formatter now records the names #define'd above each line and renders
such a label line unsplit, and the crashing input joins the corpus.

An unterminated block comment at the end of a file swallows the
formatter's mandatory final newline, an artifact the token view already
documents as layout; the preproc signature entry now trims it so the
invariant stays about tokens. The triggering input joins the corpus.

A bare GLOBL or DATA parsed without a single diagnostic while leaving a
nil Name in the tree, a pointer every downstream tool dereferences; TEXT
keeps a placeholder beside its error for exactly that reason, and GLOBL
and DATA now do the same. The crashing input enters the corpus.

The two inputs the expansion round-trip target was built for, the object
macro with a parenthesised body and the continuation-only macro body,
enter the seed corpus so every plain go test run replays them.
