Move cexp simplifications to match.pd
This required reinstating support for captures in the result
of a simplification. That part (genmatch.c) is by Richard B.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.

* genmatch.c (dt_simplify::gen): Skip captures that are
part of the result.
(parser::parse_expr): Allow captures in results too.
* builtins.c (fold_builtin_cexp): Delete.
(fold_builtin_1): Handle constant cexp arguments here.
* match.pd: Fold cexp(x+yi) to exp(x) * cexpi(y).
