For PR lto/47247, I updated the linker plugin API to add a new entry
point, LDPT_GET_SYMBOLS_V2, and a new symbol resolution code,
LDPR_PREVAILING_DEF_IRONLY_EXP. Ian approved the patch on the binutils
side, but it includes a change to an include file shared with gcc.
This patch to sync include/plugin-api.h with the binutils copy.

Committed at r179220.
