middle-end/106630 - avoid ping-pong between extract_muldiv and match.pd
The following avoids ping-pong between the match.pd pattern changing
(sizetype) ((a_9 + 1) * 48) to (sizetype)(a_9 + 1) * 48 and
extract_muldiv performing the reverse transform by restricting the
match.pd pattern to narrowing conversions as the comment indicates.
PR middle-end/106630
* match.pd ((T)(x * CST) -> (T)x * CST): Restrict to
narrowing conversions.
* gcc.dg/torture/pr106630.c: New testcase.
