    cmd/compile: record InlCost in export data · a509cae9
    Matthew Dempsky authored
    Previously, we were treating cross-package function calls as free for
    inlining budgeting.
    
    In theory, we should be able to recompute InlCost from the
    exported/reimported function bodies. However, that process mutates the
    structure of the Node AST enough that it doesn't preserve InlCost. To
    avoid unexpected issues, just record and restore InlCost in the export
    data.
    
    Fixes #19261.
