doc: Document TARGET_TRULY_NOOP_TRUNCATION requires trunc?i?i2 patterns.
2020-07-16 Roger Sayle <roger@nextmovesoftware.com>
gcc/ChangeLog:
* target.def (TARGET_TRULY_NOOP_TRUNCATION): Clarify that
targets that return false, indicating SUBREGs shouldn't be
used, also need to provide a trunc?i?i2 optab that performs this
truncation.
* doc/tm.texi: Regenerate.
