Because the 1st line of expr.h says,

/* Definitions for code generation pass of GNU compiler.

And neither get_condition() nor canonicalize_condition() is part of
the code generation pass.  They're RTL analysis functions.  Most of
the functions in rtlanal.c (all of them??) have their prototype in
rtl.h so it seemed like TRTD to move these prototypes there as well.

Whoops.
