This is a respin of my patchset implementing both the `dispatch` construct and 
the `adjust_args` clause to the `declare variant` directive. The original
submission can be found there: 
https://gcc.gnu.org/pipermail/gcc-patches/2024-May/652819.html.

Beside being rebased, this new iteration has the following changes:
 * Add a commit to fix an incorrect warning with `gfc_error`;
 * Add a testcase (xfailed due to PR/115271) to ensure that `adjust_args` works
 across TUs in Fortran;
 * Rule out `c_funptr` for `need_device_ptr`;
 * Fix some warnings turned into errors during bootstrapping.
 

Paul-Antoine Arras (8):
  Fix warnings for tree formats in gfc_error
