re PR target/51900 (const variable initialization always zero)
PR target/51900
* config/i386/predicates.md (symbolic_operand): Allow
UNSPEC_PCREL as PIC expression for lea.
* config/i386/winnt.c (i386_pe_binds_local_p): Reworked.
* config/i386/i386.c (ix86_delegitimize_address): Handle
UNSPEC_PCREL for none-MEM, too.
