88b8e63904 Remove powerpc.cc copy of use_plt_offset
This adds an extra flag for needs_dynamic_reloc() in order to remove
the copy of this function and use_plt_offset() in powerpc.cc, and
tweaks the powerpc get_reference_flags() to return the flag as
appropriate.  ELFv2 does not want ELFv1 behaviour here.

	* symtab.h (Symbol::Reference_flags): Add FUNC_DESC_ABI.
	(Symbol::needs_dynamic_reloc): Test new flag.
	* powerpc.cc (needs_dynamic_reloc, use_plt_offset): Delete.

f9c6b9078c Report overflow on PowerPC64 @h and @ha relocations.
This changes the behaviour of @h and @ha on PowerPC64 to report errors
on 32-bit overflow.  The motivation for this change is that on
PowerPC64, most uses of @h and @ha modifiers and their corresponding
relocations are to build up 32-bit offsets.  We'd like to know when
such offsets overflow.  Only rarely do people use @h or @ha with the
high 32-bit modifiers to build a 64-bit constant.  Those uses will now
need to use two new modifiers, @high and @higha, if the constant isn't
known at assembly time.  For now, we won't report overflow at assembly
time..

This also fixes an error when applying some of the HIGHER and HIGHEST
relocations.
