[Bug middle-end/38474] slow compilation at -O0 (callgraph optimization, inline heuristics, expand )

[steven at gcc dot gnu dot org]

For the inline heuristics, almost all time is also spent in stack slot related
stuff. The culprit is estimate_stack_frame_size (or actually,
add_alias_set__conflicts) in cfgexpand.c.
(What are we doing in cfgexpand anyway, for inlining?!?)
