Hi,
this patch splits LTO read and write timevars.  This is relelavant for benchmarking WHOPR.
Bootstrapped/regtested x86_64-linux, OK?

Honza

	* lto-stramer-out.c (pass_ipa_lto_gimple_out, pass_ipa_lto_finish_out):
	Update timevars.
	* timevar.def (TV_IPA_LTO_GIMPLE_IO, TV_IPA_LTO_DECL_IO): Remove.
	(TV_IPA_LTO_GIMPLE_IN, TV_IPA_LTO_GIMPLE_OUT, TV_IPA_LTO_DECL_IN,
	TV_IPA_LTO_DECL_OUT): New.
	* lto.c (read_cgraph_and_symbols, materialize_cgraph): Update timevars.
