Static consteval member functions were incorrectly getting a coverage mapping with zero count, making them appear as uncovered lines. Free consteval functions were already correctly excluded because EmitTopLevelDecl returns early for immediate functions. The fix adds an isImmediateFunction() check in HandleInlineMemberFunction before adding deferred coverage mappings, consistent with the top-level check. Fixes #164448.
