exp_dist.adb (Build_TypeCode_Call): Remove incorrect processing for Itypes.

2005-07-04  Thomas Quinot  <quinot@adacore.com>

	* exp_dist.adb (Build_TypeCode_Call): Remove incorrect processing for
	Itypes. Itypes are really unexpected there.
	(Build_TypeCode_Function): Generalise special processing for Itypes to
	handle the case of numeric implicit base types as well as enumerated
	ones.
