* sem.adb (Analyze): Add processing for loop parameter specifications.
* sem_ch4.adb (Analyze_Quantified_Expression): Reimplemented. The
routine no longer creates a copy of the original QE. All
constituents of a QE are now preanalyzed and resolved.
* sem_ch5.adb (Analyze_Iteration_Scheme): Remove the guard which
bypasses all processing when the iteration scheme is related to a
QE. Relovate the code which analyzes loop parameter specifications
to a separate routine. (Analyze_Iterator_Specification):
Preanalyze the iterator name. This action was originally
done in Analyze_Iteration_Scheme. Update the check which
detects an iterator specification in the context of a QE.
(Analyze_Loop_Parameter_Specification): New routine. This
procedure allows for a stand-alone analysis of a loop parameter
specification without the need of a parent iteration scheme. Add
code to update the type of the loop variable when the range
generates an itype and the context is a QE.
(Pre_Analyze_Range): Renamed to Preanalyze_Range. Update all references
to the routine.

Ignore any loop scopes generated for QEs when detecting an expression
function as the scopes are cosmetic and do not appear in the tree.
(Resolve_Quantified_Expression): Removed. All resolution of
QE constituents is now performed during analysis. This ensures
that loop variables appearing in array aggregates are properly
resolved.
