This is a respin of my patchset implementing both the `dispatch` construct and the `adjust_args` clause to the `declare variant` directive. The previous submission can be found there: https://gcc.gnu.org/pipermail/gcc-patches/2024-August/659719.html
Compared to v3, this new iteration handles Tobias's comments on the ME patch (https://gcc.gnu.org/pipermail/gcc-patches/2024-August/660921.html). In particular, it defines and uses a new internal function (namely IFN_GOMP_DISPATCH) to allow the middle end to more easily and accurately find the dispatch call. This is important when the single function call we are interested in is sandwiched in a sequence of pre- and post-call statements, or when the same function is call several times within the dispatch body.
