Sync libiberty/ & include/ with GCC
...
Note this brings in the interface files for libcc1/G++ as well, which
we will be needing in GDB soon anyway. That commit renamed a method
in the C interface and that required a small update to GDB's compile/
code, which I've included that in this patch to keep the tree
building.

SH FDPIC backend support
...
gcc/ChangeLog

to library functions.

constants for FDPIC.

(sh_cannot_copy_insn_p): Inhibit copying insns that are FDPIC
PC-relative call sites.
(expand_ashiftrt): Adapt invocation of function_symbol.
