[[merged with trunk rev.164348, so improved MELT runtime!]]
* gcc/melt-runtime.h: improved comments.
(melt_debug_garbcoll, melt_debuggc_eprintf): Moved from melt-runtime.c.
(melt_obmag_string): New declaration.
(struct meltobject_st, struct meltclosure_st, struct
meltroutine_st, struct meltmixbigint_st, struct meltstring_st):
using GTY variable_size and @@MELTGTY@@ comment.
(melt_mark_special): added debug print.
* gcc/melt-runtime.c: Improved comments.
Include bversion.h, realmpfr.h, gimple-pretty-print.h.
(ggc_force_collect) Declared external.
(melt_forward_counter): Added.
(melt_obmag_string): New function.
(melt_alptr_1, melt_alptr_2, melt_break_alptr_1_at)
(melt_break_alptr_2_at, melt_break_alptr_1,melt_break_alptr_1)
(melt_allocate_young_gc_zone, melt_free_young_gc_zone): New.
(delete_special, meltgc_make_special): Improved debug printf and
use melt_break_alptr_1...
(ggc_alloc_*) macros defined for backport to GCC 4.5
(melt_forwarded_copy): Don't clear the new destination zone in old
GGC heap.
(meltgc_add_out_raw_len): Use ggc_alloc_atomic.
(meltgc_raw_new_mappointers, meltgc_raw_put_mappointers)
(meltgc_raw_remove_mappointers): Corrected length argument to
ggc_alloc_cleared_vec_entrypointermelt_st.
(melt_really_initialize): Call melt_allocate_young_gc_zone.
(melt_initialize): Set flag_plugin_added.
(melt_val2passflag): TODO_verify_loops only in GCC 4.5
