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.

The one-blank rule before a new block skipped every line that followed a
TEXT directive, not just the function's first label, so a TEXT with an
empty body ran straight into the next declaration. The exemption now
applies to labels only, and the directive shapes around GLOBL and DATA
ranges are pinned.

The canonical spelling of a #define line glued a '(' to the macro name
whatever the input's spacing, turning an object macro whose body opens
with a parenthesis into a parameterised one, and it flattened the
backslash continuations of a multi-line body into one physical line,
fusing the statements the expansion splits at those boundaries. Both
change what a valid file assembles to, so renderPreproc now keeps the
name's adjacency (the same column check the preprocessor applies) and
restores the continuation boundaries from the token positions.
