This patch generalises fold-const.[hc] routines to use combined_fn
instead of built_in_function. It also updates gimple-ssa-backprop,c
since the update is simple and it avoids churn on the call to
negate_mathfn_p.
Tested on x86_64-linux-gnu, aarch64-linux-gnu and arm-linux-gnueabi.
OK to install?
Thanks,

[I've attached a -b form of the patch too since it's easier to read.]
Thanks for that. I was thinking that would have made one of the later
ones easier to read, but it was small enough not to really matter.
