checks.adb (Determine_Range): Increase cache size for checks.

	* checks.adb (Determine_Range): Increase cache size for checks.
	Minor reformatting

	* exp_ch6.adb: Minor reformatting
	(Expand_N_Subprogram_Body): Reset Is_Pure for any subprogram that has
	a parameter whose root type is System.Address, since treating such
	subprograms as pure in the code generator is almost surely a mistake
	that will lead to unexpected results.

	* exp_util.adb (Remove_Side_Effects): Clean up old ??? comment and
	change handling of conversions.

	* g-regexp.adb: Use System.IO instead of Ada.Text_IO.
