[PATCH,fortran]: fix for PRs 32797 and 32800

["Christopher D. Rickett" <crickett at lanl dot gov>]

hi all,

the attached patch is for the PRs 32797 and 32800.  the problem with 32797 
was that the result was implicitly typed and the verify_bind_c_sym wasn't 
catching it.  for 32800, the arguments to c_f_pointer were not getting 
sorted before being analyzed.

bootstrapped and regtested on x86 and x86_64 linux with no new failures.

Chris

	check the actual args against the formal, sorting them if
	necessary.
