gold patch committed: Add -x/--discard-locals

[Ian Lance Taylor]

I committed this patch to gold to add the -x/--discard-all option.  I
also fixed the handling of a local symbol which requires a dynamic
symbol table entry when -X/--discard-locals is in effect.

	PR 10670
	* options.h (class General_options): Add -x/--discard-all.
	* object.cc (Sized_relobj::do_count_local_symbols): Handle
	--discard-all.  If the local symbol needs a dynamic entry, check
	that before handling --discard-locals.
