	* MELT-Plugin-Makefile: Able to make upgrade-melt as a
	plugin. Works for GCC 5.0. Remove GCC 4.7 old stuff.

	**@@@ UNSTABLE since libmelt-ana-gimple.melt not compiling, but
	translator painfully bootstrapping!!@@@@ }}

	* toplev.c: Merged manually by keeping MELT extra stuff.
	* toplev.h: Likewise.
	* gengtype.c: Add "melt-runtime.h" in list, but merged with trunk.

	* melt-runtime.h (MELT_VERSION_STRING): Bump to "1.2-pre-merged".
	(meltgc_walk_gimple_seq): Remove.
	(gt_ggc_mx_gimple_statement_d): Same for GCC 4.9 & 5.0

	* melt-runtime.cc: Update copyright year.
	(ggc_alloc_cleared_melt_valuevector_st, melt_resize_scangcvect):
	Call ggc_internal_cleared_alloc.
	(melt_val2passflag): Skip TODO_verify_ssa, TODO_verify_flow,
	TODO_verify_stmts, TODO_verify_rtl_sharing for GCC 5.0.
	(meltgc_walkstmt_cb, meltgc_walktree_cb)
	(melt_tree_walk_frame_size, meltgc_walk_gimple_seq): Remove.
	(melt_gt_ggc_mx_gimple_seq_d): Call
	gt_ggc_mx_gimple_statement_base.
	* melt-build-script.tpl: Update copyright year. Don't symlink
	meltrunsup.h anymore.
	* melt-build-script.sh: Regenerate.

	* melt/warmelt-base.melt: Update copyright year.
	(valdesc_object, valdesc_mapobjects, valdesc_mapstrings)
	(valdesc_multiple, valdesc_closure, valdesc_routine, valdesc_hook)
	(valdesc_bucketlongs, valdesc_jsonobject, valdesc_string)

	(valdesc_double, valdesc_mixint, valdesc_mixloc)
	(valdesc_mixbigint, valdesc_real, valdesc_special_data): Use
	ggc_internal_alloc & ggc_internal_cleared_alloc for GCC 5.0.
	(json_canonical_name): Use ISUPPER, ISALPHA, TOUPPER instead of
	their standard <ctype.h> lowercase macros.
	* melt/warmelt-modes.melt: Update copyright year.
	(generate_runtypesupport_forwcopy_fun): Emit both GCC 4.9 & 5.0
	compatible code.
	* melt/libmelt-ana-base.melt: Update copyright year.
	* melt/libmelt-ana-gimple.melt: TO BE IMPROVED
	* melt/generated/*: Painfully regenerated several times thru GCC
	4.9 MELT plugin.
