[Bug tree-optimization/42462] [4.5 Regression] wrong-code with computed-goto

This weird side-effect of IPA-SRA is caused by a bug in
compute_inline_parameters which should pass node->decl instead of
current_function_decl to its helper functions.  I am about to test the
following patch which fixes this problem:
