Fangrui Song cd0ab2428f [ELF] --icf: do not fold preemptible symbols 
Fixes PR44124.

A preemptible symbol may refer to a different definition at runtime.
When comparing a pair of relocations, if they refer to different
symbols, and either symbol is preemptible, the two containing sections
should be considered different.
