ipa/94245 - avoid folding when we want an ADDR_EXPR

Browse Source 
Another case where build_fold_addr_expr is harmful.

2020-03-23  Richard Biener  <rguenther@suse.de>

	PR ipa/94245
	* ipa-prop.c (ipa_read_jump_function): Build the ADDR_EXRP
	directly rather than also folding it via build_fold_addr_expr.
