+Print the full structure of all rtx insns beginning at $.

+Uses variable debug_rtx_count to control number of insns printed:
+  debug_rtx_count > 0: print from $ on.
+  debug_rtx_count < 0: print a window around $.
+
+There is also debug_rtx_find (rtx, uid) that will scan a list for UID and print
+it using debug_rtx_list. Usage example: set $foo=debug_rtx_find(first, 42)
