Summary: D25878, which added support for !absolute_symbol for normal X86 ISel, did not add support for materializing references to absolute symbols for X86 FastISel. This causes build failures because FastISel generates PC-relative relocations for absolute symbols. Fall back to normal ISel for references to !absolute_symbol GVs. Fix for PR38200.
