Fix bootstrap failure with --enable-gather-detailed-mem-stats.

This patch restores bootstrap when detailed memory stats are enabled.
No functional changes.

Tested on x86_64.  Committed to trunk.

2012-11-27  Diego Novillo  <dnovillo@google.com>

	* vec.h: Replace 'class vec' with 'struct vec' everywhere.
	(ggc_internal_cleared_alloc_stat): Remove.
	(va_gc::reserve): Add PASS_MEM_STAT to ggc_realloc_stat call.
	(va_stack::reserve): Add PASS_MEM_STAT to va_heap::reserve call.
	(vec<T, A, vl_embed>::copy): Replace ALONE_MEM_STAT_DECL with
	ALONE_CXX_MEM_STAT_INFO.
	(vec_safe_reserve): Replace MEM_STAT_DECL with CXX_MEM_STAT_INFO.
	(vec_safe_reserve_exact): Likewise.
	(vec_alloc): Likewise.
	(vec_safe_grow): Likewise.
	(vec_safe_grow_cleared): Likewise.
	(vec_safe_push): Likewise.
	(vec_safe_insert): Likewise.
	(vec_safe_splice): Likewise.
	(vec_alloc): Likewise.
	(vec_check_alloc): Likewise.
